-- Class: DebugShortcuts

--

-- This allows for debugging shortcuts that perform tasks that aid

-- debugging -- e.g. skipping to a certain level or making a player sprite

-- invincible. These can be triggered by a hotkey at any time, or appear

-- in a list in the debug console.

--

-- Out of the box:

--		- Control-Alt-F toggles fullscreen

--		- Control-Alt-Q quits the app.

--		- Control-Alt-P deactivates the view.

-- 		- Control-Alt-R reloads all app code from on disk.

--		- Control-Alt-S saves a screenshot to the app's directory --

--		  see https://love2d.org/wiki/love.filesystem for where this is.
