Holding the Shift key on your keyboard for too long may change the settings of some of the other buttons. Thus, you may no longer be able to type certains characters (like commas, numbers both on the left and on the right side of the keyboard, some letters), or to use Caps Lock, even after restarting your computer. You may also find that using the shift key types the wrong sign. Fortunately, there are some simple solutions that worked for our users. Depending on your keyboard, there might be different ways to fix it. If you want to know the steps to follow, read on.
The first simple solution is to hold down both Shift keys and the ALT button at the same time. This is the equivalent of switching back and forth between European and American keyboard. If this doesn’t work for you, then you should check the other solutions we found.
A variation of this is required if you find that your shift key is typing the wrong sign. For example, you are trying to type the @ symbol, and seeing something else.
If the different combinations of keys didn’t fix the problem, you should consider the following: first go to the “Control panel”. Then in the “Keyboard tab” click on “Accessibility options”. Then click on the settings buttons for Sticky keys, Filter keys and Toggle keys and deselect the option to use shortcut.
Pressing five times the Shift key will turn off the Sticky Keys (or will turn them on, if they are already off).
We hope that you find these solutions useful and that your problem is now fixed!
