New SendKeyEvent and SetKeyTarget actions. These let you define SendKeyEvent actions that send a specified key to a target window. The target window can be changed at runtime with the SetKeyTarget action.
Add RaiseTemp action. This has the same effect as giving the <raise>yes</raise> option to next/prevwindow but makes it optional and keybindable, so if W-Tab is nextwindow, you can have W-q as raisetemp.
