// @description	Hotkeys for BvS Zombjas
// @version     3
// @history		3 Removed searching from contextual action button. Tweaked hospital strategy (heal infection, then fight, then heal HP). Added special key for searching specifically (L). version by taltamir.
// @history		2 Optimized strategy. added heal infection, heal HP, and search. Instead of keys surrounding G, use numpad and keys surrounding S (left and right handed options). switched include to match. rewrote almost all code. fixed bug where key detected press rather than relese despite notes saying otherwise. version by taltamir
