keybinding
----------

Create hotkeys that will run DFHack commands. Like any other command it can be
used at any time from the console, but bindings are not remembered between runs
of the game unless re-created in `dfhack.init`.

Hotkeys can be any combinations of Ctrl/Alt/Shift with A-Z, 0-9, F1-F12, or
``\```.

Usage:

- ``keybinding``
  Show some useful information, including the current game context.
- ``keybinding list <key>``
  List bindings active for the key combination.
- ``keybinding clear <key> [<key>...]``
  Remove bindings for the specified keys.
- ``keybinding add <key> "cmdline" ["cmdline"...]``
  Add bindings for the specified key.
- ``keybinding set <key> "cmdline" ["cmdline"...]``
  Clear, and then add bindings for the specified key.

The ``<key>`` parameter above has the following **case-sensitive** syntax::

    [Ctrl-][Alt-][Shift-]KEY[@context[|context...]]

where the ``KEY`` part can be any recognized key and [] denote optional parts.

When multiple commands are bound to the same key combination, DFHack selects
the first applicable one. Later ``add`` commands, and earlier entries within one
``add`` command have priority. Commands that are not specifically intended for
use as a hotkey are always considered applicable.

The ``context`` part in the key specifier above can be used to explicitly
restrict the UI state where the binding would be applicable.

Only bindings with a ``context`` tag that either matches the current context
fully, or is a prefix ending at a ``/`` boundary would be considered for
execution, i.e. when in context ``foo/bar/baz``, keybindings restricted to any
of ``@foo/bar/baz``, ``@foo/bar``, ``@foo``, or none will be active.

Multiple contexts can be specified by separating them with a pipe (``|``) - for
example, ``@foo|bar|baz/foo`` would match anything under ``@foo``, ``@bar``, or
``@baz/foo``.

Interactive commands like `liquids` cannot be used as hotkeys.

Examples:

- ``keybinding add Alt-F1 hotkeys``
  Bind Alt-F1 to run the `hotkeys` command on any screen at any time.
- ``keybinding add Alt-F@dwarfmode gui/quickfort``
  Bind Alt-F to run `gui/quickfort`, but only when on a screen that shows the
  main map.
