A macro to cancel casting current spell and clear spellcasting queue?

[Savie]

As far as I can tell, pressing "x" twice is the best way, or you could just do the "x" then /cast; I also play a healer.

-- if you press it too much, you can lose your target, close windows, etc. I also have no idea how to put Escape key into macro.

If you choose to go this route, there is a set up you can make to target your previous target, but I can't remember how this is done.
