Backspace Browser Navigation

Here is something:

• that is useful and timesaving
  
• that I didn't know until a couple of days ago
  
• that I learned by noticing someone else doing it
  
• that you may already know, Mr. or Ms. Smarty
  
• that I don't know how I didn't know, I just didn't, you know?
  
• that is even better than the way I used to do it, which I thought was pretty cool in the first place
  
• that works at least in superior browsers like Firefox, as well as in inferior crap like IE

And here it is:
the "Backspace" key (or "Delete" key on Macs) is a browser shortcut for the "go back one page" command.

Sure you can click the little back-arrow button, but if you're a keyboard kind of person like me, then you don't always want to reach all the way over there for the mouse. What I've been using for years instead is Alt-Left-Arrow (or Cmd-Left-Arrow on my Macs). But that's twice as many keys, and worse, a two-handed operation. So, while it will be a little weird to retrain my brain that the "delete the previous character you typed" key is also sometimes the "go back one page" key, it will be well worth it. Just think of all the free time I'll have now!

Those of you who already knew this, why in God's name didn't you tell me? Those of you who didn't, you're welcome.
