Shoulda Taken a Left at Albuquerque
You can celebrate Learn a New Shortcut Day in any of several ways.
You can find a shorter way to drive to your destination. Although, these days Google Maps or your phone generally gives you the shortest way already. Sometimes it gives you the fastest way, which may not be the shortest, so you can check on that as a possible way to celebrate.
You can find a keyboard shortcut on your computer that you haven't used before.
Mac users, you may know that Shift-Command-3 lets you do a screenshot, but do you know what Shift-Command-4 lets you do?
PC users, how about Ctrl-A or Ctrl-Z?
Besides the above options, there innumerable things you can do that could probably be done quicker (and maybe better) by discovering a shortcut.
If you've got one or more such tasks, why not share them with the rest of us?
Go ahead, make our day.
