It is a good idea to know at least a few keyboard shortcuts for the PC when using your computer.
The following keyboard shortcuts will save you a lot of time and energy when put to use.
The following keyboard shortcuts are located at the very top of your keyboard. I want to not that a lot of these shortcuts will work on most programs and devices. For example the F1 key is always for help. Take a look at the follow chart for basic keyboard shortcuts.
|Esc||Cancel the current task|
|F2||Rename the selected item|
|F3||Search for a file or folder|
|F4||Display the address bar list in Windows Explorer|
|Alt+F4||Close the active item or exit the active program|
|Ctrl+F4||Close the active document (in programs that allow you to have multiple documents open simultaneously)|
|F5 (or Ctrl+R)||Refresh the active window|
|F6||Cycle through screen elements in a window or on the desktop|
|F10||Activate the menu bar in the active program|
|Shift+F10||Display the shortcut menu for the selected item|
The next group of keyboard shortcuts that I want to share with you will be using the the arrow, CTRL, ALT, and Shift keys. These shortcuts will be use frequently for things like copy and paste.

A few more keyboard shortcuts that I think dessearve a mention is the Ctrl + tab that will move you through tabs and if you add shift to the keyboard shortcut it will move you back through the tabs. Shift + tab will move you through options backward and tab forward. This is one we all should know but Enter replaces the mouse left click, try it on any website.
