Do you find it difficult to press multiple keys at once? Sticky Keys lets you use Shift, Ctrl, Alt or Windows logo keys by pressing one key at a time.
If pressing CTRL+ALT+DEL is an acrobatic feat, you can set up Sticky Keys. With Sticky Keys you can hit one key at a time in a keyboard shortcut. You can even set it to make a noise so you know it’s working.
You can set up Sticky Keys in Windows 7, Windows Vista or Windows XP.
Press your “SHIFT” key 5 times in a row, then click on the link, to get going with Sticky Keys in Windows 7 or Windows Vista.
You can also access Set up Sticky Keys option via All Control Panel Items > Ease of Access Center > Set up Sticky Keys
