Thanks for the quick reply! I previously watched that video and selected option 1. At the very end of my config file is this line:
input_enable_hotkey = nul
Based on what he said I removed that line from the bottom of the file and changed this section to:
# Alternatively, all hotkeys for keyboard could be disabled by the user. input_enable_hotkey = alt
Rebooted and unfortunately they still aren’t working.
