Jump and crouch - same button

[Jopp-gh]

I would like to bind two shortcuts to button A, example:

• tap once = jump (hold 0.5sec)
• long press = crouch (hold 1sec)

I tried various combinations under advanced to hold / release options, but didn't succeed to make it work.

Jump triggers always, even if I put jump after crouch, it just follows after.

Probably this key combo can't be assigned, but it would be very useful: Because both jump and crouch eat away 2 buttons!
