One of the handouts that I give to participants in my InDesign on-site training seminars is a quick reference guide to all the keyboard shortcuts in InDesign. If you haven't had the good fortune to have me do InDesign training at your company, you can still get a copy of the keyboard shortcut guide copy of the keyboard shortcut guide here. I've worked hard to organize the shortcuts into recognizable language, and still have them all fit on two sides of a letter-size page. There are both CS2 and CS3 versions, for Macintosh and Windows platforms. I hope you find these useful!
