If you liked my previous article on Photoshop shortcuts, you'll probably find this post useful. Here are 26 Illustrator shortcuts that can help you to speed up productivity. I use most of them (in fact, I can't work without them). Most of shortcuts listed in this article aren't documented in the software, so keep reading and you’re sure to find at least one new trick to put up your sleeve. Enjoy!
