Get Quick Reference Posters for Office, Photoshop, Windows, Linux, Other Geeky Topics

Ever wish you had a handy quick reference for the apps you use the most often? You're in luck, because you can download PDFs of dozens of reference posters from TechPosters.

This site is full of dozens of posters for all sorts of geeky topics. There's a lot of stuff here that only an IT geek's mom could love, like a Unicode character chart, Unix commands, programming references, and architectural diagrams for operating systems.

But don't let that put you off. Browse the categories on the right side of the page, and you'll find references charts for Microsoft Office apps, photo editing programs like Photoshop, and even Apple stuff. The site isn't bound to the latest and greatest versions, either: You'll be able to find guides to versions of Word from 97 to present, for example.

When you find what you like, you can download it and keep it on your PC or print it and hang it on your wall.

And don't forget -- these posters go great with the interactive troubleshooting flowcharts I told you about last week. [via gHacks]
