Every once in a while I need to take a screenshot or screen capture in OS X. (So what’s the difference between a screenshot and a screen capture? None really, as far as I know. But you have to include both so people searching for either will find these nuggets of wisdom.) Invariably I have to look up how to do this: I don’t have a great head for keyboard shortcuts. 😛 So, I decided to keep a notes page on how to do it. Leave a comment if you use a different method or workflow.
This first set of commands I got from an Apple support page.
Takes image of whole screen and saves it to desktop.
Gives you a crosshair, which you can use to select an area of the screen. Also saves to desktop.
Whole screen, saves to clipboard.
Crosshair area selection, saves to clipboard.
My friend Joan (V-C, not S) recommended a program called Skitch, which not only captures screenshots, but also allows you to mark them up.
