Many thanks to Steve (W4JM) who writes:

Here is what I use for POTA activations to keep the key stable.

A clip board, carpet tape on the back to hold a carpet pad in place.

The Begali I put two slots in the clip board on either side of the traveler where then I could use a tie wrap to pull it secure to the board.

On the CW Morse I just used two screws with locking nuts to secure it to the board.

Your right hand holds the pencil while sending and your wrist weighs down on the clip board and I printed some POTA logs on excel to fit to the left of the key.

I hope this helps some of your readers with key movements. I now have my left hand to drink my coffee.

Clever and simple! I love it, Steve. Thanks for sharing!
