 * Windows Three toggle keys. **



You can toggle between capitals and lower-case letters.
 * Caps Lock: **

You can toggle between numbers and no numbers. When the Num Lock is off, then you can use the other functions on the keys instead, i.e. the arrows, Home, End, etc (see chart below).

This key is not used for much toggling of anything anymore Modern software does not usually support Scroll Lock, but there are exceptions, such as Microsoft Excel. In Excel when the Scroll Lock is off, you go from cell to cell with your arrow keys. With Scroll Lock on, you can scroll the whole page with the arrow keys on the number pad; the cells stay in the same place and do not scroll with you. You can even turn Scroll Lock on and off from within Excel. Thus, if you happen to find software that works with Scroll lock, you can turn it on and pause what is on the screen while you scroll, or when it is off, just scroll normally.

Standard Keyboard:



There you go; toggle keys in a nut shell.

One added note: Sometimes toggle keys can accidentally get turned on (especially the Caps Lock key).

You can make your computer beep & flash the next time it happens. The first thing you will need to do is get the computer to beep when you click the Caps Lock key. Here’s how: XP Users, click the **Start** button, **Control Panel.** Open the **Accessibility Options** Icon. On the **Keyboard tab**, click the **Use Toggle Keys** checkbox. That is it for the beeping part. Next, you need to get your screen to flash at you. Here’s how: From the Accessibility Options screen, click the **Sound tab** and check the Next, select **Flash active window** from the **Choose the visual warning** drop down box. That is it. Open your favourite word processor and click your **Caps Lock** key.
 * Use SoundSentry** checkbox.
 * Click OK until you are clear of property and settings screens**.
