+fullscreenmodes
+===============
+
+Description
+-----------
+This patch adds keybindings to toggle fullscreen and fake fullscreen
+on the focused client. Alternating between the two doesn't cause the
+client to leave fullscreen. It also adds fullscreen and fakefullscreen
+rules for starting applications in fullscreen.
+

+
+Notes
+-----
+Most of the code comes from [actualfullscreen](../actualfullscreen) and [selectivefakefullscreen](../selectivefakefullscreen)
+but these patches are not compatible. However the authors of those
+projects should get credit for the original fullscreen functionality
+that inspired this patch.
