The Advanced branch under Configuration - Editor has the following options:
Allow low ASCII values to be entered (usually control codes)
This setting allows the input of "low values" to be entered such as control codes while editing. Normally these would be ignored.
Load/Restore printer settings
The editor tries to communicate with the printer driver when it loads and shuts down (to preserve settings). If a network printer is specified as the default printer and not available this may cause a delay on startup while the editor tries to find the printer on the network. If this option is not selected then the editor does not communicate with the printer.
ESC key hides output window when visible
If this option is selected the output window may be dismissed by pressing the Escape key if the output window has focus.
Grouped undo
If this option is selected undo will be executed on a word-by-word rather than character-by-character basis. If this setting is toggled during the editing of a document (and the undo buffer is partially created with both settings) the undo functionality will reflect the settings in place at the time the document was created. This could cause part of the text in a file to be undone as grouped characters and part to be undone character-by-character.
Auto-Save modified documents when application loses focus
If this option is selected all modified documents will be saved when focus shifts to another application.
Preserve leading spaces when joining lines
If this option is selected, leading spaces will be retained when the join lines command is executed.
