16.1.2 Input Editor Commands

Keyboard input to accept can be edited until an activation keystroke is typed to terminate it. If the input cannot be parsed after an activation keystroke is entered, it must be edited and re-activated. The input editor has several keystroke commands, as listed in Table 4., Input Editor Keystroke Commands. Prefix numeric arguments to input editor commands can be entered using digits and the minus sign (-) with CONTROL and META (as in Emacs).

The function :add-input-editor-command can be used to bind one or more keys to an input editor command. Any keystroke can be an input editor command, but by convention only keystrokes that do not correspond to graphic characters should be used.

The input also supports "numeric arguments" (such as C-0 , C-1 , M-0 , etc.) that modify the behavior of the input editing commands. For instance, the motion and deletion commands will be repeated as many times as specified by the numeric argument. Furthermore, the accumulated numeric argument will be passed to the command processor in such a way that substitute-numerical-marker can be used to insert the numeric argument into a command that was read via a keystroke accelerator.
