At times, the Tab randomly stops working. Once I restart the computer it's working again.

Has anyone seen something like this before?

I'm using a TypeMatrix keyboard.

Intel(R) Core 2 Duo CPU E8400 @ 3.00Ghz 3.62 GB Ram Dell Optiplex 780

  • What happens if you plug in another keyboard or use the onscreen keyboard? – Supercereal May 21 '12 at 18:14
  • Didn't know there was an onscreen keyboard. I like that. That's useful for testing things. Thanks! – Ben_Coding May 22 '12 at 20:26

Some other causes of this issue have been identified:

  • KVM Switches
  • Synergy (keyboard and mouse sharing with multiple computers over the network)
  • Windows thinks some key is stuck: try pressing Ctrl and Alt
  • StickyKeys is enabled: try pressing the Windows Key twice to turn it off
  • Xerox Printer Drivers (Xerox Job Tracker, Xerox PrintingScout)
  • Logmein, TeamViewer, Citrix XenDesktop

    Team viewer was opened on my system, I closed it, it is working now. – paul Sep 6 '16 at 17:13

    Another vote for Teamviewer! I have a Windows Surface with attached keyboard, plus a wireless keyboard. [Tab] wasn't working on either of them. Shut down Teamviewer, instantly [Tab] started working again! – CJ Dennis Nov 30 '17 at 3:26

    @paul Thanks, TeamViewer was the case! That's weired, that had never happened before. – David Refoua Aug 2 '18 at 17:16

In my case, it was that inside TeamViewer (remote system running Windows 10), I had opened the Start menu (you know, by clicking on the little window icon in the bottom left corner). As long as that was up, Tab was not working on my local system!

I didn't have to reboot or disconnect my Teamviewer session, only to minimize the Start menu on the remote system. Then Tab worked again!

Maybe the keyboard is getting faulty. How old is it? Do you press tab a lot? I know that keyboards are very resilient, my daughter beats on mine daily, but they do break. I agree with Kyle, try using another keyboard to see if that fixes it.

    Restarting Windows actually did the trick. Something with this specific keyboard though. – Ben_Coding Aug 14 '12 at 15:25
