MAPPINGS *telescope.mappings*
|telescope.mappings| is used to configure the keybindings within a telescope
picker. These keybinds are only local to the picker window and will be cleared
once you exit the picker.
We provide multiple different ways of configuring, as described below, to
provide an easy to use experience for changing the default behavior of
telescope or extending for your own purposes.
To see many of the builtin actions that you can use as values for this table,
see |telescope.actions|
Format is:

mode = { ..keys }

normal).

requiring an action or by writing your own function)
