Locking Out User From Alt+Tab

Locking Out User From Alt+Tab

Hello all,

I am setting up some Wyse S50 terminals using Wyse Linux v6 to use the Ericom PowerTerm program. I have everything set up as much as I could figure out to lock down the user, getting rid of the bottom taskbar, menu bar for terminal, uninstalling the browser, etc. However one action remains that can cause problems, while in the terminal window, a user could hit Alt+Tab and go to the Connection Manager, which would allow them to edit settings, or go to the Control Panel, which is not good.

Essentially I'm asking if anyone knows a way to disable the Alt+Tab function in the whole OS or just for the Ericom terminal program. I've tried key mapping in the terminal, but Alt+Tab won't map.

I appreciate any light anyone can shed on this problem.

Thank you,
