1. description of problem
I was working on something on my Windows 8 laptop and suddenly a blue border appeared and followed every window or button I click on. As a side effect, tapping on things on the screen stopped working. For example, tapping on a button simply resulted in the blue border coming to that button instead of the button being pressed. You might have experienced the same problem.
2. what causes it
When the blue border appears on your Windows 8 laptop, what really happened is that you unknowingly pressed some keyboard shortcut that opens Narrator, which is a program (shipped with Windows) that narrates things on the screen to you.
3. solution (how to get out of it)
To get out of this, locate an unfamiliar new icon on the task bar. That’s the icon for “Narrator Settings”. If you’re using a mouse (or a laptop trackpad), click on that icon to switch to the Narrator Settings window and then you’ll know how to get out. If you’re using only touch (i.e., using your hybrid laptop as a tablet), you can tap on the icon, and Windows will say “Narrator Settings button. double tap to activate”, which you will not hear if you have muted the laptop audio. So the next step is you double tap on that icon to switch to Narrator Settings window and then you’ll know how to get out.
