Alt-Key sets column mode
There are two selection modes: All characters between Start and End. Or a rectangular area between Start and End. You can switch between those modes by pressing Alt and selecting with the mouse. This does not work under X, because the Alt+Mouse key is almost always already used by the window manager.
When inserting new lines (e.g. through pressing Return or Enter key), the editor will indent the caret on the new line with the same amount of leading white space as the preceding line.
If the cursor is behind or in front of a bracket, highlight matching bracket.
Show gutter hints
Show hints when mouse is over the gutter (the bar on the left side of the source editor).
Show special characters
Spaces are shown as dots and invalid characters as question marks.
Use syntax highlight
Use colors and styles for different tokens. You can setup the highlighting in the editor options / colors.
Show scroll hint
Started, but not yet implemented: Shows a hint of the visible line numbers when scrolling vertically.
Drag Drop editing
Allows you to select a block of text and drag it within the document to another location.
Not implemented yet: Allows the editor accept file drops.
Half page scroll
When scrolling with page-up and page-down commands, only scroll a half page at a time.
Keep cursor X position
When moving through lines w/o Cursor Past EOL, keeps the X position of the cursor.
Keep cursor blinking, even if losing focus. The is needed on some systems, where the focus messages do not work properly.
Cursor skips selection
When there is a selection and you press the left arrow, the cursor will go to the start of the selection.
Right mouse moves caret
When clicking with the right mouse for a popup menu, move the cursor to that location.
Scroll by one less
Forces scrolling to be one less line.
Scroll past end of file
Allows the cursor to go past the end of file marker.
Scroll past end of line
Allows the cursor to go past the last character into the white space at the end of a line.
Home key jumps to nearest start
home key jumps to line start if nearer, similar to visual studio.
Always visible cursor
Move cursor to be always visible when scrolling.
When tabbing, the cursor will go to the next non-white space character of the previous line. If the current line is longer than the previous, it will look for a longer line in front.
Tabs to spaces
When editing lines the editor adds spaces instead of tabs. The rest of the lines will not be altered and the tabs are kept. To convert all tabs of a file select the whole file (Ctrl-A) and use Main menu / Edit/ tabs to spaces.
Tab indents blocks
When active <Tab> and <Shift><Tab> act as block indent, unindent when text is selected.
Trim trailing spaces
Spaces at the end of lines will be trimmed and not saved. This applies only to edited lines.
Undo after save
Keep the Undo list on save.
When undoing/redoing actions, handle all continuous changes of the same kind in one call instead of undoing/redoing each command separately.
Double click line
Select line on double click.
Pressing Ctrl will highlight the word under the mouse cursor.
Show a close button on each source editor tab. Not all widgetsets support this. At the moment only the gtk interface.
Find text at cursor
When invoking the 'Find' dialog, fetch the word at the cursor and put it into the Find field.
Copy word on copy none
If nothing is selected and user presses Copy (Ctrl-C), the editor selects the word and copy that. Same for cutting.
Amount of spaces a block is indented. For example with Ctrl+I.
Maximum number of Undo steps.
Maximum spaces for Tab characters.
Margin and gutter
