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.
