Flash can be a little slow to navigate around, luckily alot of common functions have keyboard shortcuts. I made this Flash Cheat Sheet for all common shortcuts to shorten development time.
I didn't write the cheat sheet. I formatted this page, so you can print it out in a nice readable pdf version (there's also a .png version).

If there's any mistakes, or anything that I've left out, let me know and I'll fix it.
