Try to cringe the player (the german says ducken)

This day I was trying to add a player animation to a key, to make the player cringe. I am wondering that this seems not to be there. Hm, I was looking into the code and found the config.cs and the default.bind.cs file which controlls the animations. If config.cs isn't there, all the bindings belongs to default.bind.cs. Ok, I was looking with show, which animation of the player is proper working for 'cringe'. I think the 'land' animation will do a good job. But now, how do I bind a key into default.bind.cs to play the land animation ??
Or I'm completely wrong ?
