Since I can't download a better memory, I tried to think of a quick way to have a cheat sheet readily available. I first tried a text file, but I would have to launch an application each time I wanted to look at it. I thought of embedding the text in a desktop picture, and decided that would be too boring.
What I hit on doing was to take a screenshot of just the text of my cheat sheet, make a new folder with the screenshot inside, and set my screenshot as the background of the folder. Now that folder lives minimized in my dock, and I can pop it open any time I need to 'remember' a keyboard shortcut.
