In a comment to one of my posts on calc, Sue D. Nymme (love that handle) mentioned that he was working on a quick reference for calc and kindly provided a sneak preview. Now he reports that he’s ready to release it to the world.
Check out his github repository for the project to get a copy. It’s a really excellent resource that has the subject matter arranged in a more logical way than the others quick references that I’ve seen. You can print it (see qref-config.ps) as 1 page per sheet, a half sheet booklet, or a quarter sheet booklet depending on your needs. There are directions in the README for assembling the output into a booklet. To generate a copy, just edit qref-config.ps to choose how many pages you want on each sheet and then type make.
If you’re a calc user—and you really should be—you’ll definitely want to definitely check this cheat sheet out. I use mine all the time.
