I have a full screen game playing in borderless windowed mode. That lets me alt+tab out in a reasonable timeframe. My problem is that when I aim down, the taskbar comes up. When I fire my weapon, I lose control of the orientation of my character in the game which is very detrimental to my performance and game outcome. How do I suppress the taskbar for the duration of the game whilst enabling me to disable suppression with a multi-key press if I need it?
