+Subject: [PATCH] Multikey: Run different actions for single keybinding based
+ on # of keypresses
+
+Changed keypress code to allow keybindings to be selectively dispatched when
+tapped a specific # of times as specified by the new npresses field on the
+Key struct.
+
+In the example added to the config.def.h, the tiling layout is set when
+Mod+w is tapped once, float layout is set when Mod+w is tapped twice,
+and monocole layout is set when Mod+w is tapped three times (or held down).

+Description
+-----------
+This patch allows you to use a single key combination to trigger different
+functions based on the number of times you press the key combination
+consecutively within a short period of time. This is accomplished by modifying
+the `Key` struct to add a new int field `npresses` which can be:
+
+ 0 = Trigger keybinding on 1 keypress (ignoring multikey functionality)
+ 1 = Trigger keybinding on 1 keypress
+ 2 = Trigger keybinding on 2 successive keypresess
+ 3 = Trigger keybinding on 3 successive keypresess
+ ...n = Trigger keybinding on n successive keypresses
+
+The maximum / last value set for the key combination can also be triggered by
+holding the key down.
+
+In the example added to the config.def.h, the tiling layout is set when
+Mod+w is tapped once, float layout is set when Mod+w is tapped twice, and
+monocole layout is set when Mod+w is tapped three times (or held down).
