As well as using your mouse to operate software, you can also use your keyboard to perform specific functions. This page provides a list of keyboard shortcuts which you may find useful.

How to use a keyboard shortcut 

Traditionally, keyboard shortcuts are written like so: Alt + F1. This means that you should press the Alt and F1 keys simultaneously. This is normally best achieved by holding down the modifier key (such as Ctrl or Alt) and then pressing the second key once. You can then release the modifier key. 

 

Finding application-specific keyboard shortcuts

 While there are many standard keyboard shortcuts (see below), most applications also have keyboard shortcuts which are specific to themselves. These can normally be found in the pull-down menus at the top of the application's screen. The example below shows a menu in OpenOffice.org Writer, with the keyboard shortcuts highlighted:
