[fossfreedom]

See this answer - the window-shuffler files in that folder should be the ones you need to copy and modify

Rebinding Alt+Q

Create a folder called ~/.local/share/budgie-extras-daemon copy the files tilix_alt.bde and tilix_f12.bde found in /usr/share/budgie-extras-daemon into your local folder that you created above. Edit the command you want in the .bde files that you want to bind the shortcuts with. Logout and login.
