Key Bindings

Haskeline provides a line-editing user interface with many interactivity commands. Currently the user may choose either Emacs or Vi style bindings by editing the ~/.haskeline file; see System.Console.Haskeline.Prefs for more details.

Definitions:

• ^A: Control-A
• M-A: Option-A
• [printable char]: Any Unicode printable character (Data.Char.isPrint returns True)
• [kill]: the console's 'kill' character (usually ^U)

Commands shared by both bindings

Left/right arrow	move the cursor left/right by one character
Return	finish the line entry
Backspace	delete the character left of the cursor
Delete	delete the character right of the cursor
[printable char]	insert a character
Up/down arrow	move backwards/forwards in the command history
Tab	run tab completion
^L	clear the screen
^R	search backwards in history
^S	search forwards in history
[kill]	delete until the start of the line

Emacs-specific bindings

^A	move to the start of the line
^E	move to the end of the line
^B	move left one character
^F	move right one char
^D	delete the character to the right of the cursor
	^D is treated as an EOF if the input line is empty and the last character pressed was not also ^D.
M-F	move forwards one word
M-b	move backward one word
M-w	delete backwards one "big word"
M-backspace	delete backwards one word
M-D	delete forwards one word
^K	delete until the end of the line
