|
|
|
|
This function supports use-package's :bind-keymap keyword. It
|
|
works by binding the given key sequence to an invocation of this
|

function for a particular keymap. The keymap is expected to be

|
defined by the package. In this way, loading the package is

deferred until the prefix key sequence is pressed."
