Alt + Spacebar to behave like alt + tab

[Japistos]

Thank you for the great software. I like it because I use a wacom with my left hand and my right hand is on the keyboard, so I've finally got an easier way of switching windows without having to reach over to alt+tab. Is there a possibility to make alt+space able to cycle through open apps by holding down alt and pressing spacebar (like alt+tab)? And, could we have an option to allow alt+space to automatically switch to the highlighted app when releasing it (like alt+tab)?

Thank you in advance
