Although keyboard shortcuts can be real time-savers, sometimes it's hard to press multiple keys at once, (especially while you're eating a sandwich or holding your phone in one hand). The Windows Sticky Keys feature lets you press one key at a time as you enter a shortcut. You can turn on Sticky Keys permanently by using the Control Panel's Ease of Access Center options.  |
