I found this web site by Tom Pearce that has a Filemaker template that will import your workspace text file and convert it into a printable keyboard format. If you look at the image you can see that it shows all the hot keys, with the correct modifier keys, and all of the keyboard shortcuts.
There are some instructions to follow, so please read them carefully. I was able to follow the instructions easily.
For me, the main strategy would be to print out the standard workspace first. Use this to figure out what you want to change. Edit your workspace, then export your workspace to a text file.
The exported text file is then imported into the Filemaker document. Filemaker will put all the hot keys and shortcuts in the correct location. Then print out your workspace from the Filemaker document.
