WINDOWS LOGO (between CTRL and ALT) -- Hit this key and your Start menu appears; is that not faster than going over with your mouse and clicking?

WINDOWS LOGO + F: Find files or folders. This saves you from opening the Windows Explorer and selecting find from the menu. Now you have a one-click computer search!

F1 -- In Windows applications, and in the OS, F1 is a universal call to the app's help system.

F2 -- In Windows Explorer, use F2 to rename files or folders. This is faster than right-clicking and easier that clicking inside the file or folder name and waiting for the input field to become available.

SHIFT+DELETE: Deletes an item immediately without placing it in the Recycle Bin. Works in most Explorer sub-systems or program navigations.

F5 -- This is a universal "Refresh" command, which works in many Windows applications. Use it to refresh your Explorer file system, browser and html editors.

CTRL + C To copy

CTRL + V To paste

CTRL + Z: Undo your last action. This works in both Windows and Mac machines and, like CTRL + C for copy and CTRL + V for paste, is a universal keyboard command. Undo is handy for quickly erasing your last action in just about any program.

CTRL + A: Select all the items in the current window. This is a great shortcut, which in combination with Copy and Paste, will have you flying around your screen!
