Suggestion: "Left Alt" and "Tab" should be cleared of bindings

I've noticed in the new default control scheme "Left Alt" switches between "Cursor Mode" and "Aim Mode" and "Tab" is "Lock Target".

I think this is an error and I think in many modern online games these keys are kept clear of anything too important or intrusive due to their very frequent use by many players who are alt+tabbing in and out of the game, this is an especially regular occurrence in the MMO genre I believe and caused a lot of frustration for me almost immediately when I had my game constantly switching to "Aim Mode" for no reason when I was tabbing in and out of it.

Absolutely yes. It was the first change I made to the new keymap, i.e. LAlt on set team target as I had before, because except for those occasions it has no effect. Haven't settled on where to move lock target yet but it has to go elsewhere the moment I start needing to alt-tab out in a hurry regardless of whether the avatar is in a position to rest.
