solved End key and numpad 1 ley (also end) makes a sound

[Father Cool]

When I press the end key or the numpad 1 key (which is also technically an end key) it plays a sound. This happens only when DCS is the focus window. In every aircraft and in every menu it makes the sound. Out of game it doesn't. No idea what's going on but its very annoying. It didn't used to do it until a couple of updates ago.

Solved: It was my Steam screenshot key bound to 'end'.

False alarm.
