hotkeys Menu overlay widget
-------------------
.. image:: ../images/hotkeys.png The in-game hotkeys menu is registered with the `overlay` framework and can be
enabled as a hotspot in the upper-left corner of the screen. You can bring up
the menu by hovering the mouse cursor over the hotspot and can select a command
to run from the list by clicking on it with the mouse or by using the keyboard
to select a command with the arrow keys and hitting :kbd:`Enter`.
A short description of the command will appear in a nearby textbox. If you'd
like to see the full help text for the command or edit the command before
running, you can open it for editing in `gui/launcher` by right clicking on the
command, left clicking on the arrow to the left of the command, or by pressing
the right arrow key while the command is selected.
