@wflint,
There is no printed manual for TRS2019, but i notice that you have TANE, and there is one in the material that comes with TANE. I'm not sure of the page numbers, but I think the keyboard shortcuts are from pages 249 to 255. I have used them with both TANE and TRS2019, and they seem to work OK in both, but no guarantees, especially in 2019. They do print very nicely.
