Is there a way to override system/user keybindings for Lubuntu 16.04 when a particular application opens?
I have created an entry in ~/.config/openbox/lubuntu-rc.xml to force the specific application to open in fullscreen by default. The thing is, I do not want my users to have access to anything else while using said application. It is a google-chrome app for testing k-12 students' progress. Various keybindings allow the students to break the validity of the test by Alt+Tab to a browser to look up the answer, or opening the run command to bring up Galculator to find the answer, etc.
I can disable keybindings altogether for that user account. This is not my preferred method as some of those keybindings are useful for average use, just not while this test is being proctored.
Anybody out there have any suggestions as to maybe further editing the particular entry to use a custom keybinding list? Or maybe disallow all keybindings with the exception of Ctrl+Q to quit the program?
