			Some attributes of an open console window can not be changed from the menu(see the Note at the end of this section).
	Read the manual of the [[UserDoc:Shell_Prefs\|shell preferences editor]]

			The GUI shows several areas in the window, used to select settings of particular variables as defaults. There are three "pages" of settings, selected by clicking one or other of the Tabs at the top of the window.

			Appearance Page
			Text Font
			Cursor Style
			ClickTab Labels
			Emulation Options
			Text Colors Page
			Palette
			Foreground Color
			Background Color
			Sample Text
			Completion Page
			Name Completion
			Command Completion
			Other Options
			Options Page
			Display History
			Text Options
			Save Settings Options

			Note: The preferences editor can be called from the console menu, if the console has been opened with the "History" or "Tabbed" attributes. You
			can exit from the preferences editor in the normal way with "Save", "Use" or "Cancel". If you select "Use", there are more settings that specify
			how the changed settings will affect other Shells and windows.

			When making changes to the console attributes from the menu, be aware that attributes of the window layout can not be changed in the current window.
			If you wish to change one or more of these attributes, you must "Save" or "Use" the settings and specify that the changes are to apply to "Future
			Windows". The new attribute(s) (for example, "Box around Text") will then be used when future windows are opened.

			Also, there are some attributes that can not be changed in the current Shell.
			If the current Shell is displayed in a window with Tabs, you can change the attribute from the Menu, then clone the Shell and the new Shell will show the modified attribute(s).

			While using the shell you will probably have to move around in the current line and to change some text to fix errors. Here are the keyboard shortcuts you can use to make your work with the shell easier.
	Typing commands in a shell.

			* ''Left-arrow''
			Moves cursor one character to the left.

			* ''Alt Left-arrow''
			Moves cursor to the beginning of the current word, or to the beginning of the previous word, or to the beginning of the line.

			* ''Shift Left-arrow'', ''Ctrl A'', ''Home'' ("PC"-style keyboards only)
			Moves cursor to the beginning of the line.

			* ''Right-arrow''
			Moves cursor one character to the right.

			* ''Alt Right-arrow''
			Moves cursor to the beginning of the next word, or to the end of the line.

			* ''Shift Right-arrow'', ''Ctrl Z'', ''End'' ("PC"-style keyboards only)
			Moves cursor to the end of the line.

			* ''Backspace''
			Deletes the character to the left of the cursor. All characters at and to the right of the cursor are shifted one character left to fill in the
			gap. The cursor moves one character left.

			* ''Alt Backspace''
			Deletes the whole word to the left of the cursor.

			* ''Delete''
			Deletes the character under the cursor. All characters to the right of the cursor are shifted one character left to fill in the gap. The cursor does
			not move.

			* ''Alt Delete''
			Deletes the whole word to the right of the cursor.

			* ''Ctrl H''
			Deletes the previous character (same as Backspace).

			* ''Ctrl M''
			Processes the command line (same as Enter).

			* ''Ctrl J''
			Adds a line feed.

			* ''Ctrl X''
			Deletes the current line.

			* ''Ctrl K''
			Deletes everything from the cursor forward to the end of the line.

			* ''Ctrl Y''
			Replaces the characters deleted with Ctrl/K.

			* ''Ctrl U''
			Deletes everything from the cursor backward to the start of the line.
