I downloaded the original P2ATC_commands.pdf cheat sheet a couple of years ago and I had it still on my computer. You can now find it at:

Based on the OP's cheat sheet I created a slightly more extensive P2ATC cheat sheet that now spans 2 pages.
It has the same layout as the original cheat sheet (full credits to the OP).
