Only can type in caps. It acts like the shift key is stuck

Its not my keyboard. I have tried multiple keyboards.

Everything I type is in CAPS.

When I try and click on a line it acts like the Shift key is held down and selects stuff.

Please Help

I still find this happening occasionally. To avoid a DenverCoder9 situation: I find that if I lock the screen and unlock it, it fixes this.

Check your Universal Access settings. You can find it by going to the Ubuntu Dash (Click the Ubuntu icon at the top left, or press the Super/"Windows" key>), and typing in the word sticky. Make sure Sticky keys setting is turned off.

If you press and hold the Shift key for about 5 seconds it should turn the Shift sticky on/off.

Double tap the Shift key to turn off all caps.
