`api`.mode_exit({exit_char}) *libmodal-lua-api.mode_exit()*
Use |feedkeys()| to send an {exit_char} which signals a |libmodal-mode| or
|libmodal-prompt| to stop listening for input.
It is not usually necessary to specify {exit_char}. It is only necessary
to do so when |libmodal-mode|'s {supressExit} flag is active, because
it is possible that the user has set up some non-default character which
should be used to exit the mode (see |libmodal-examples-supress-exit|).
Parameters: ~
{exit_char} (Optional) The character used to exit the mode, or
|libmodal-lua-globals.ESC_NR| by default.
Can be a character number (see |char2nr()|) or a string.
Example: ~
>
local libmodal = require('libmodal')
-- This function is called every time the user presses a key.
local function _instruction()
-- Exit the mode after pressing any key.
libmodal.utils.api.mode_exit()
end
