How to remove display list under game tab?

I’m using Input.GetKeyDown(KeyCode.Space) to check whether Spacebar has been pressed.
When I run my game in editor and press spacebar, the display list will always pop up instead of letting my codes handle it. It’s really annoying, how do I fix this?

File > Build Settings
select Android and click Build
