A while back, I wrote an article on left-hand keyboard shortcuts for Windows. I like to use them, so I don't have to take my right hand off the mouse. With the release of Windows 8, Microsoft added in more shortcuts, primarily for the Start screen. So here is a list of Windows 8 keyboard shortcuts for just your left hand.

General Windows keyboard shortcuts

In 1995, Microsoft introduced Windows 95 with a new feature called the Start menu. To make it easy to use, they added a key to the standard keyboard and called it the Windows logo key. Microsoft even added a hand full of keyboard shortcuts to go along with it. The Windows logo key is now standard on Windows based computers, and Windows 8 takes full advantage of it.

One of the most useful items I use daily is keyboard shortcuts. Especially shortcuts that I can perform with just my left hand, allowing me to keep my right hand on the mouse. You can use keyboard shortcuts to open frequently used files, folders, and programs like File Explorer. Windows has a ton of built-in keyboard shortcuts (see links at the bottom of this article), plus you can create your own custom keyboard shortcuts. Here are my favorite left-hand keyboard shortcuts:

Press	To
+ E	Open My Computer / File Explorer
+ R	Open the Run dialog box
+ D	Display the desktop
+ F	Search for a file or folder (Windows 7 / 8.1)
+ S	Search for a file or folder using Cortana (Windows 10)
CTRL + A	Select all
CTRL + X	Cut
CTRL + C	Copy
CTRL+ V	Paste
CTRL + ALT + (KEY)	Custom keyboard shortcut (see below)

create your own Windows keyboard shortcuts

You can create keyboard shortcuts that use CTRL + ALT + (your choice of a key) for frequently used files, folders, and programs. You will need to have a shortcut to the file, folder, or program you want to open first. You can use an existing shortcut (on your desktop or the Start menu) or create a new one. Once you have a shortcut:

1. Right-click on the shortcut
2. From the context menu, click Properties
3. On the Properties box, select the Shortcut tab
   
4. Click inside the Shortcut key box and press the key in which you want to combine with CTRL + ALT

Note:
You can not use the following keys for keyboard shortcuts: ESC, ENTER, TAB, SPACEBAR, PRINT SCREEN, SHIFT, or BACKSPACE.
