I am left handed, though I do somethings right-handed. I'm certainly not ambidextrous. It is just curious to me what things I do with the right hand.

1. Play guitar
2. Use a computer mouse
3. Use a key to unlock a door. This is the one I just discovered and prompted me to start this list. I had a big bag in my right hand, and a smaller bag under my left arm. So, I reached with my left hand into my coat's right pocket to get the key. It was surprisiingly hard to use the key with my left hand.
4. I can write right-handed, pretty slow, but legibile. In class sometimes I have a different color marker in each hand and write with whichever is appropriate at the time.
5. I throw a backhanded disc/frisbee throw with my right hand (and horribly left-handed) and I throw forehand with my left (and horribly right-handed).
6. Snap my fingers, middle and thumb. Loud and clean with right, not as clear with left
7. Others will be added as I think of them...
