Gmail on a Mac

This one is going to drive me nuts. On a pc using gmail you can type an email, press tab and then enter and it sends the email. When you press tab it moves focus to the send button. On this mac that doesn't happen. Tab never performs like I expect, at least on web pages. Driving me nuts. Funny how such a little thing can make such a difference. But I at least need a comparable key combination so I don't have to touch my mouse in gmail.

Just found the answer to this. System Preferences/Keyboard & Mouse/Keyboard Shortcuts then at the bottom you see "Full Keyboard Access". Make sure you choose the "All Controls" option and it works like a charm. Wahoooo!
