There are 100+ keyboard shortcuts available for Windows 8, but there are several you'll want to remember because you'll use them often.
In April 2012, Greg Shultz created a free cheat sheet of 100 Windows 8 keyboard shortcuts. That download contained just about every keyboard shortcut you could imagine. Those shortcuts are still valid of course, but if you are like me you can only remember a few shortcuts at a time, so you want to remember the ones that will be most useful.
So, while I highly recommend that you take advantage of the free PDF download listing of 100 Windows 8 keyboard shortcuts, I also recommend that you commit the following 10 keyboard shortcuts to memory, because you are going to need to access these features often and, for efficiency's sake, it's best to have them at the ready.
