It seems that I learn a new, hidden shortcut, trick or tip about Photoshop virtually every day (CS4 here...). I thought I'd share these with any PS users out there, when I come across them. They might not be new to some people, but they are all things that I find that make my workflow and productivity better...

Today: The Brush tool:

Click once where you want to start a line. Then while holding Shift, click where you want to finish the line. This will create a straight line with the Brush Tool.

I didn't know that, until today. :-)
That is all.
