Subject: Using The Numeric Keyboard to Control the Mouse Pointer

If using an optical mouse is too difficult for you or you have a faulty 
mouse, you can enable the Mouse Key feature. Mouse Key is an 
accessibility feature that allows you to use the numeric keyboard 
instead of the mouse.

You can find the feature under the accessibility category; in windows 
system the category is called "Ease of Access".

Many GUI systems allows you to open a system menu by pressing 
<ctrl>+<esc>, and then navigate using the tab key and the arrows to find 
what you need.

Now, learning how to use the numeric keyboard is pretty easy:

* The keys '2','4','6' and '8' have arrows on them.

* The keys '1','3','7','9' are in the corners, so they are used for 
diagonal movements.

* The key '/','*' and '-' are used to select the mouse key to click or 
depress. Find their mouse equivalents according to their places in the 
top row.

* The key '5' - single click the selected key. It is useful to mark 
texts for copying and drag scrollbars.

* The key '0' - depress (or hold down) the selected key.

* The key '+' - double-click the selected key.

* The key '.' - to release the depressed key.
