# Keyboard shortcuts

# Editing Shortcuts

Shortcut	Description
`Ctrl` + `a`	move to the beginning of the line
`Ctrl` + `e`	move to the end of the line
`Ctrl` + `k`	Kill the text from the current cursor position to the end of the line.
`Ctrl` + `u`	Kill the text from the current cursor position to the beginning of the line
`Ctrl` + `w`	Kill the word behind the current cursor position
`Alt` + `b`	move backward one word
`Alt` + `f`	move forward one word
`Ctrl` + `Alt` + `e`	shell expand line
`Ctrl` + `y`	Yank the most recently killed text back into the buffer at the cursor.
`Alt` + `y`	Rotate through killed text. You can only do this if the prior command is `Ctrl` + `y` or `Alt` + `y`.

Killing text will delete text, but save it so that the user can reinsert it by yanking. Similar to cut and paste except that the text is placed on a kill ring which allows for storing more than one set of text to be yanked back on to the command line.

You can find out more in the emacs manual (opens new window).

# Custome Key Bindings

With the bind command it is possible to define custom key bindings.

The next example bind an Alt + w to >/dev/null 2>&1:

bind '"\ew"':"\" >/dev/null 2>&1\""

If you want to execute the line immediately add \C-m (Enter) to it:

bind '"\ew"':"\" >/dev/null 2>&1\C-m\""

# Remarks

bind -P show all configured shortcuts.
