One of the biggest hassles in the Gmail program on Android is that the buttons you're going to want to use the most aren't easy to find. Sure, "Archive," "Label" and "Delete are simply two button pushes (underneath the menu) away, but Reply, Reply to All and Forward are on-screen buttons that appear at the bottom of every email. This can be a huge hassle -- huge as in "Oh my god, I might not be able to be a power-emailer on this thing" because who knows how long an email may be -- sometimes there's old threads in the chain of emails and sometimes, well, and email is just freaking long.
Good news, though, if you have the keyboard out, there are convenient one-push keyboard shortcuts for most of your popular email functions. We list them for you (plus a bonus feature), after the break!
