CS2 flash bind

Use a different key

The example uses mouse4. These keys are common alternatives; copy the version you want.

bind "x" "use weapon_flashbang"

bind "v" "use weapon_flashbang"

How to remove this bind

Unbind the key it sits on. If you used another key, put that key in the quotes instead.

unbind "mouse4"

Then bind the key back to what it did before, or run binddefaults to reset every key to Valve's defaults.
