Keyboard shortcuts

Remarks:

bind -P show all configured shortcuts.

Recall Shortcuts

Shortcut	Description
`Ctrl` + `r`	search the history backwards
`Ctrl` + `p`	previous command in history
`Ctrl` + `n`	next command in history
`Ctrl` + `g`	quit history searching mode
`Alt` + `.`	use the last word of the previous command
	repeat to get the last word of the previous + 1 command
`Alt` + `n` `Alt` + `.`	use the nth word of the previous command
`!!` + `Return`	execute the last command again (useful when you forgot sudo: `sudo !!`)

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.
