AmigaOS Manual: Workbench Preferences

This chapter explains the Preferences editors found in the Prefs drawer. These editors allow you to customize your Amiga environment by:

• Choosing a keyboard type
• Setting your preferred language
• Changing the Workbench screen display
• Changing the Workbench colors
• Changing the shape of the pointer
• Specifying a printer and setting it up for output
• Setting up a modem for use with the Amiga
• Setting the time and date

This chapter contains the following Preferences editor information:

• Contents of the Prefs drawer
• Editor menus
• Presets drawer
• Descriptions of each Preferences editor

Prefs Drawer

The Prefs drawer contains the icons for the Preferences editors and the Preset drawer. Figure 5-1 illustrates the Preferences editors window.

Preferences Window

The following editors are listed in the order in which they are described in this chapter:

Font	For changing the fonts used in the different areas of the screen.
IControl	For choosing miscellaneous system options, such as the key used for screen drag.
Input	For changing the mouse speeds, key repeat speeds, and selecting keyboard type.
Locale	For selecting the language and locality.
Overscan	For adjusting the size of the display area for text and for graphics.
Palette	For changing the Workbench colors.
Pointer	For changing the size, shape, and color of the mouse pointer and busy pointer.
Printer	For specifying the printer driver that matches your printer and for specifying options, such as paper size and margin width.
PrinterGfx	For setting up your printer to print graphics.
PrinterPS	For controlling output to a PostScript printer.
ScreenMode	For choosing a different monitor display mode.
Serial	For setting the specifications for the serial port, which is used to communicate through modems or networking systems.
Sound	For determining the sound your Amiga produces for its display beep.
Time	For setting the time and date.
WBPattern	For selecting or creating background patterns for the Workbench windows and screen.
Presets	For storing different Preferences editor configurations changed through the Project menu.

Editor Menus and Presets Drawer

With the exception of Time, each editor has three menus: Project, Edit, and Settings. The Project menu lets you save and load Prefs preset files, which allow you to quickly change to different configurations. By default, these files are saved in the Presets drawer (SYS:Prefs/Presets), although they can be saved to any location you specify. If you save icons for the files (by selecting Create Icons?), you can activate the settings by opening the file's icon, rather than opening the actual editor.

When you save settings in the Preferences editors by clicking on the Save button, the system stores those settings in the following location:

SYS:Prefs/ENV-Archive/Sys/editorx.prefs

where SYS: is the name of the volume containing the file and editorx is the name of the specific Preferences editor. The settings saved to the Env-Archive drawer are the ones used when you boot. We recommend when you use the Save As option that you use the path provided or a completely different path than this for storing Preset files.

Project Menu

The following Project menu options let you save the editor settings to a specific file and open previously saved files:

Open	Loads the information from a specified preset file.
Save As	Specify the preset file in which to save the currently displayed settings. The requester provides a default file name in the Presets drawer. Change this to a different name if you have more than one preset for that editor.
Quit	Exits the editor without performing any changes. The same as Cancel gadget.

Edit Menu

The Edit menu options allow you to restore previously used settings or the default settings. The options are:

Reset to Defaults	Returns the editor settings to the system default settings.
Last Saved	Returns the editor settings to the last settings you saved with the Save gadget (not the Save As item).
Restore	Returns the editor to the settings displayed when you opened the editor first.

The WBPattern and Pointer Edit Menus have the following additional options:

Cut	Copies and clears the whole work area to the Clipboard.
Copy	Copies the whole work area to the Clipboard.
Paste	Replaces the whole work area with the last thing cut or copied.
Erase	Deletes everything in the work area.
Undo	Undoes the last action performed.
Load Image	Opens a file requester for entering the name of an image file to use as a background pattern or picture.

These options make editing patterns and pointer images easier. Use Cut, Copy, and Paste to transfer images between the editor and a Clipboard-aware program with more extensive drawing tools, such as IconEdit. Use Load Image to import any standard IFF bitmap image into the editor. (Images larger than the editor work area are cut off on the bottom and right sides when loaded or pasted.)

Settings Menu

The Settings menu contains the Create Icons? Item that allows you to save project icons for the preset files. For example, if you save printer specifications to the SYS:Prefs/Presets/Printer.pre file, an icon for the file appears in the Presets window. Double-click on the icon to activate the file's settings.

Using the Presets Drawer

Open the Presets drawer and double-click on an Presets Project icon to use its settings. Or open the editor, choose the Open menu item, and use the Load requester to select the preset. Select Use to use the settings until you reboot or open another editor file.

Font Editor

The Font editor changes fonts used on the Amiga.

For information on fonts and on using the Font Preferences editor, see Chapter 8.

IControl Editor

The IControl editor, illustrated in Figure 5-2, lets you change system settings, such as the screen drag qualifier key and the text gadget filter.

IControl Preferences Editor Window

Screen Drag

The Screen Drag gadget specifies other keys that can be used in addition to, or in place of, the left Amiga key as the qualifier for dragging the Workbench screen. This is useful if, for example, an application uses left Amiga and the selection button for other functions.

The available keys are Shift, Ctrl, left Amiga, and Alt. To select a key, click on its check box.

If you select Ctrl, you must hold down Ctrl to drag the screen. If Ctrl and Shift are selected, you must hold down both Ctrl and Shift to drag the screen.

Screen Menu Snap

Screen Menu Snap is provided for users who work with screens that are larger than the monitor's display area. Normally the Workbench menus appear at the top left corner of the screen. If the left-most side of the screen is not visible, Screen Menu Snap shifts the Workbench screen so that the menus are still accessible. The screen shifts only while the menu button is held down.

Text Gadget Filter

The Text Gadget Filter affects whether control characters function as characters or as editing commands when entered into text gadgets. A control character is a key combination (usually Ctrl and an alphabetical key) that normally performs a certain function.

The standard control characters for text entry are:

Ctrl+M	Same as pressing Return.
Ctrl+H	Deletes one character to the left of the cursor (same as Backspace).
Ctrl+X	Deletes the entire line.
Ctrl+U	Deletes all characters to the left of the cursor.
Ctrl+K	Deletes all characters from the cursor to the end of the line.
Left Arrow	Moves the cursor one character to the left.
Right Arrow	Moves the cursor one character to the right.
Ctrl+A	Moves the cursor to the beginning of the line.
Ctrl+Z	Moves the cursor to the end of the line.

When Text Gadget Filter is selected, entering one of these control characters when the cursor is in a non-numeric text gadget has the function indicated above. When the filtering is off, the control character is included in the string entered; on the screen the control characters appear as an open box or other nonstandard character.

You can insert control characters into the text gadget whether filtering is turned on or not by pressing Ctrl+left Amiga along with the desired alphabetical key. For example, to enter Ctrl+M into the text gadget, press Ctrl+left Amiga+M.

Note
In certain windows with several text gadgets, pressing Tab moves the cursor to the next text gadget. In these windows, even if the Text gadget filter is off, you must still press left Amiga+Tab to enter a Tab into the gadget.

Avoid Flicker

The Avoid Flicker option prevents a back screen from becoming interlaced when the front screen is pulled down to reveal it. The default for this option is on.

Mode Promotion

The Mode Promotion gadget controls the software de-interlacing feature of Amigas with the AGA chip set. Selecting Mode Promotion allows NTSC and PAL screens opened by applications to be promoted to a non-flickering display mode. We recommend that you turn this option off when doing video work. For more information about Mode Promotion, see Chapter 7.

Input Editor

The Input editor allows you to change the speed at which the mouse and keyboard operate and to select your keyboard type. Figure 5-3 illustrates the Input-Preferences editor window.

Input Preferences Editor Window

Mouse Speed

The Mouse Speed slider determines how fast the mouse pointer moves across the screen relative to mouse movement. The faster the pointer moves across the screen, the less surface space and effort is needed to move the mouse.

Choose from three mouse pointer speeds: 1, 2, and 3, where 1 is the slowest and 3 is the fastest. Set the mouse pointer speed by dragging the slider bar until the desired value is displayed. The mouse speed takes effect while you set it, allowing you to try each speed without exiting the editor. The default value is 3.

Acceleration

The Acceleration feature is used for moving the pointer quickly over large screen areas while retaining fine control for smaller movements. If acceleration is on, the pointer speed remains constant within a small area. However, as the pointer is moved further across the screen, its speed increases, moving it quickly over a large area of the screen.

Select the check box to turn acceleration on or off. The default value is off.

Double-Click Delay

The Double-Click Delay slider determines how fast you click the selection button to register a double-click.

The range is from 1 to 200, with 1 being the least delay. The Show Double-Click gadget shows the amount of time for the selected value by displaying shading in the gadget for the length of the delay. The default value is 75, which allows approximately one second between clicks.

Test your chosen speed by double-clicking in the Test Double-Click gadget. When the double-click takes place within the allotted time, a Double-Clicked message appears next to the gadget; if not, a Too Slow message appears.

Key Repeat Delay

Most of the keys on the keyboard automatically repeat when held down. Change the delay that occurs before the key repeats with the Key Repeat Delay slider.

The current setting is shown next to the slider. The range is from 1 to 75, with 1 being the least delay. Drag the slider bar to the right to increase the delay and to the left to decrease it. The default value is 30.

Key Repeat Rate

The Key Repeat Rate slider determines the rate at which the keys repeat after the initial key repeat delay.

The range is from 1 to 125, where 1 is the slowest. Drag the slider bar to the right to increase the speed and to the left to decrease it. The default value is 100.

Keyboard Test

The Keyboard Test gadget allows you to test the settings chosen for the key repeat delay, the key repeat rate, and the keyboard type.

Select the gadget and hold down one of the alphabetic keys on the keyboard. The Keyboard Test gadget shows the character for that key in the selected keyboard type, repeating according to the current key delay and key repeat rate.

Keyboard Type

The Keyboard Type list lets you select the appropriate keyboard type for your localized system. The correct keyboard type matches the characters printed on your keyboard's keys and gives you quick access to the special characters that are part of your language and locale. If you are using a keyboard other than USA, you can use dead keys to produce accented characters. See the KeyShow description in Chapter 10 for dead key information.

Note
If your keyboard type is not the default American, you must activate your appropriate keymap/keyboard. Consult your dealer if you are not sure which keymap/keyboard you should use.

Choosing a particular keyboard type activates the corresponding keymap file in the Devs/Keymaps drawer. Select your keyboard type in the Input Preferences editor by clicking on it.

The available keymaps and the corresponding keyboards are:

Keymap	Keyboard Type
gb	British
cdn	Canadien Français
dk	Dansk
d	Deutsch
usa2	Dvorak
e	Español
f	Français
i	Italiana
n	Norsk
po	Português
ch2	Schweiz
ch1	Suisse
s	Svenskt

If your keyboard type does not appear in the Keyboard Type list, it means that the corresponding keymap is not present in the Devs/Keymaps drawer. Install the corresponding keymap to correct this using the following steps:

1. Insert either the Storage floppy disk or the disk containing the Storage drawer in any drive.
2. Open the Storage window and then open the Keymaps drawer.
3. Drag the correct icon into the Devs/Keymaps drawer.

Then this is complete, you can return to the Input Preferences editor to activate your keyboard type. To check your keyboard layout, use the KeyShow program in the Tools drawer. For more information about KeyShow, see Chapter 10.

Locale Editor

The Locale editor lets you choose the languages with which you interact with the Amiga. The default setting is USA English; however, you can use the Locale editor to choose another language. See Chapter 6 for a full description of the Locale editor.

Overscan Editor

The Overscan editor, illustrated in Figure 5-4, enlarges the size of your screen to use the extra space normally unused around the edges of the monitor screen, known as the overscan area.

Overscan Preferences Editor Window

The Monitor Types available reflect the monitor drivers that are currently active. Monitor files that are in DEVS:Monitors when you boot are automatically activated. Each monitor type controls a set of display modes, called a display group.

When you change the overscan values for a particular monitor type, all modes within that type are affected. To change the overscan values for a monitor type, select its monitor type from the scrolling list. The selected group is highlighted. See Chapter 7 for listings of the maximum available overscan sizes for each display mode.

Text and Graphics Overscan

The Overscan editor allows you to set two different types of overscan: Text and Graphics. Most users can ignore the difference and set both to the same maximum value appropriate for their monitor. Having two settings can help those who use a television set as a monitor or whose monitor is unable to display a sharp image across its entire width.

The screen size and position set as Text overscan is the setting used by the Workbench screen. It can be any size between the minimum and maximum Dimensions limits, but it cannot be any larger than the Graphics overscan setting. If it is enlarged beyond the current Graphics setting, the Graphics setting is adjusted to match.

The screen size and position set as Graphics overscan are the limits within which the Text overscan area must fit and is the maximum for application screens in that display group. Graphics overscan can be any size between the minimum and maximum Dimensions limits. If the Graphics overscan area is sized or moved, the current Text overscan setting is adjusted as necessary to fit.

Using Different Text and Graphics Overscan

A television image normally extends beyond the edges of the screen itself, so that the outermost edges of the image are not visible. If some part of the Amiga's display runs off the edges of the screen on your television set or monitor or is distorted at the edges, use different Text and Graphics overscan settings.

Confine the Workbench and application screens that must remain legible to the visible area by setting Text overscan to the minimum size and centering it on the screen. The Graphics overscan area can be larger, allowing graphic images and other material for which legibility is less important to fill more of the monitor screen.

Overscan Edit Screens

Selecting either the Edit Text Size or Edit Graphics Size gadgets displays a separate screen, illustrated in Figure 5-5, on which you graphically adjust the overscan size. The Overscan editor allows you to set two different overscan regions.

Edit Text Size Window

The black rectangles on the screen are handles and the line connecting the handles represents the outermost area where the Amiga's output can be displayed. Enlarge the display area by pointing to a handle, holding down the selection button, and dragging the handle to the edge of the screen. Only the active handle is visible on the screen when you drag it.

Moving any part of the handle off the screen or out of the viewing area over enlarges it, losing a portion of the visible image.

For monitor types other than NTSC and PAL, there are four arrow gadgets in the lower left area of the edit screen. The arrow gadgets allow you to shift the entire display area up, down, right, and left to center it. Move the display in the direction of the arrows by clicking on them. Depending on your monitor type, it is possible to move the display too far to the right or left, causing the monitor to go out of sync. This can result in the colors fading or a total disruption of the display. Because this condition can damage you monitor, it is important not to leave it this way for an period of time. If this happens, you can use the arrow keys on the keyboard to move the display back into position or press the Escape key, which undoes any changes you made and returns to the Overscan editor window.

Use the center handle to position the display area within the viewable area when the screen is not at maximum size. By dragging the handle, you can shift the display area in any direction to center it on your monitor screen.

The Current Position figures show the x/y distance in pixels from the upper left corner of the screen to the upper left corner of the display area. Current Size shows the size of the viewable area defined by the handles.

To accept changes and return to the Overscan editor, select OK. To exit the screen without accepting any changes and return to the Overscan editor, select Cancel or press the Escape key.

Dimensions

The different sizes of the overscan areas are displayed on the right of the Overscan window. The sizes are given in number of pixels, representing the width and the height of the screen.

For PAL or NTSC groups, the sizes correspond to the sizes for a standard High Res screen. If Multiscan is selected, the sizes for a non-interlaced Productivity screen are given. All other display modes in a group are affected proportionally.

The size categories are:

Minimum	The standard, non-overscan size of a screen.
Text	The current Text Overscan size.
Graphics	The current Graphics Overscan size.
Maximum	Maximum allowable overscan size, Text or Graphics.

Palette Editor

The Palette editor, illustrated in Figure 5-6 lets you change the colors of the Workbench.

Palette Preferences Editor Window

On Amigas with the AGA chip set, the left side of the Palette Preferences editor window displays either the four or eight current Workbench colors in the selection gadget, a color wheel, a gradient intensity indicator, and color sliders that can be RGB (red, green, blue) or HSB (hue, saturation, brightness) depending on your Slider Color Model menu selection. (RGB is the default setting.)

On Amigas with the ECS chip set, a gadget labeled Color Wheel... is displayed in place of the color wheel. Click on this gadget to display a screen containing the color wheel and intensity indicator. When you have made your color selection on this screen, press OK to activate it or Cancel to cancel. Pressing their gadget returns, you to the Palette Preferences editor window.

The right side of the Palette Preferences editor window has a Color Mode cycle gadget with two settings: Multicolor Settings and 4 Color Settings. The Multicolor Settings gadget is for setting eight Workbench colors. The 4 Color Settings gadget is for setting four Workbench colors. Both modes should be set to accommodate editors and applications that use one setting or the other.

The Palette Preferences editor window displays the following nine window items for which you can select specific colors:

• Background
• Text
• Important Text
• Bright Edges
• Dark Edges
• Active Window Title Bars
• Active Window Titles
• Menu Background
• Menu Text

Below the Workbench items list is a color selection gadget containing four or eight color boxes similar to the color selection gadget above the color wheel.

Depending on the display mode, width, and height set in the ScreenMode Preferences editor, the bottom of the Palette Preferences editor window can display a sample window that changes as you change color selections. This display shows the elements contained in a typical Workbench window, including a screen title bar. If the sample does not appear on your Palette Preferences editor window, a Show Sample gadget is displayed instead. Clicking in this gadget displays the sample window showing your color selections. You can click on the items in the sample to select the elements whose colors you wish to change.

You can choose the color or item you wish to change by clicking on:

• A color box within one of the two color selection gadgets.
• An item in the window elements list.
• An item on the sample window.

The following four methods can be used to change colors or their shade:

• Using the RGB mode color sliders.
• Using the HSB mode color sliders.
• Using the color wheel.
• Using the gradient slider next to the color wheel.

Changing the black and white settings can affect the three-dimensional appearance of the screen. Be sure colors replacing black are darker than colors replacing white.

To change color using the color wheel:

1. Point to a color in the selection gadget above the color wheel or below the Workbench items list and click the selection button.
2. Point to the color intensity indicator (the highlighted dot within the color wheel) and hold down the selection button.
3. Moving the mouse pointer moves the indicator on the color wheel, changing the color in the display box and on the sample screen as the indicator moves. Release the selection button when you reach the color you want.

To change a color's shade using the gradient slider:

1. Point to a color in the selection gadget above the color wheel or below the Workbench items list and click the selection button.
2. Point to the highlighted bar within the gradient slider and hold down the selection button.
3. Moving the mouse pointer up or down within the gadget lightens and darkens the color.

To change a color in RGB mode:

1. Point to a color in the selection gadget above the color wheel or below the Workbench items list and click the selection button.
2. Use the slider gadgets to change the selected color. The color in the display box and on the sample screen changes as the bar is dragged through the slider box.

To change a color in HSB mode:

1. Point to a color in the selection gadget above the color wheel or below the Workbench items list and click the selection button.
2. Use the slider gadgets to change the selected color. The color in the display box and on the sample screen changes as the bar is dragged through the slider box.

The Hue slider changes the basic color, the Saturation slider changes the amount of color, and the brightness slider changes the lightness or darkness of the color.

In addition to the standard Preferences menus, the Palette editor also has a Presets menu item in the Edit menu that contains predetermined color settings and a Settings menu item that lets you determine which Slider Color Model to use for changing your colors.

If you have a monochrome monitor or if you choose a color setting of 2 in the ScreenMode Preferences editor, the Palette Preferences editor only displays RGB color sliders.

Pointer Editor

The Pointer editor lets you change the color, size, and shape of the mouse pointer and the busy pointer. Figure 5-7 illustrates the Pointer editor window. A magnified view of the current pointer is shown to the left. To the right are reduced copies of the pointer, showing how it looks against the Workbench colors.
