For a list of key names, see: :link:`GLFW keys
<http://www.glfw.org/docs/latest/group__keys.html>`. The name to use is the part
after the :code:`GLFW_KEY_` prefix. For a list of modifier names, see:
:link:`GLFW mods <http://www.glfw.org/docs/latest/group__mods.html>`

On Linux you can also use XKB key names to bind keys that are not supported by
GLFW. See :link:`XKB keys
<https://github.com/xkbcommon/libxkbcommon/blob/master/xkbcommon/xkbcommon-keysyms.h>`
for a list of key names. The name to use is the part after the :code:`XKB_KEY_`
prefix. Note that you should only use an XKB key name for keys that are not present
in the list of GLFW keys.

Finally, you can use raw system key codes to map keys. To see the system key code
for a key, start kitty with the :option:`kitty --debug-keyboard` option. Then kitty will
output some debug text for every key event. In that text look for ``native_code``
the value of that becomes the key name in the shortcut. For example:

.. code-block:: none

    on_key_input: glfw key: 65 native_code: 0x61 action: PRESS mods: 0x0 text: 'a'

Here, the key name for the :kbd:`A` key is :kbd:`0x61` and you can use it with::

    map ctrl+0x61 something

to map :kbd:`ctrl+a` to something.

You can use the special action :code:`no_op` to unmap a keyboard shortcut that is
assigned in the default configuration.

You can combine multiple actions to be triggered by a single shortcut, using the
syntax below::

    map key combine <separator> action1 <separator> action2 <separator> action3 ...

For example::

    map kitty_mod+e combine : new_window : next_layout

this will create a new window and switch to the next available layout

You can use multi-key shortcuts using the syntax shown below::

    map key1>key2>key3 action

For example::

    map ctrl+f>2 set_font_size 20
''')

You can also create shortcuts to go to specific tabs, with 1 being the first tab::

    map ctrl+alt+1 goto_tab 1
    map ctrl+alt+2 goto_tab 2

Just as with :code:`new_window` above, you can also pass the name of arbitrary
commands to run when using new_tab and use :code:`new_tab_with_cwd`. Finally,
if you want the new tab to open next to the current tab rather than at the
end of the tabs list, use::

    map ctrl+t new_tab !neighbor [optional cmd to run]

''')],
    'shortcuts.layout': [
            _('Layout management'), '',
            _('''\
You can also create shortcuts to switch to specific layouts::

    map ctrl+alt+s goto_layout stack

   map ctrl+alt+p last_used_layout
