I'm trying to map alt tab behavior to a mouse button using xdotool in my .xbindkeysrc. What I want to do is map something like

"xdotools keydown alt key Tab"
release b:7

but by doing this the alt key gets stuck, and it prevents my other mappings from working until I press the alt key on the keyboard. Is there a way to do this without having to press the alt key to get things unstuck? Without keydown it just switches back and forth between two windows, with keydown it behaves like I want (displaying the alt-tab switcher) but the alt key is stuck. Is there a way to unstick the key after using the alt tab switcher using xdotools?
