When you use the On-Screen Keyboard (OSK) Accessibility tool and you click the CTRL + ALT key combination, all of the alphanumeric keys become blank.

Also, if you move the pointer over a key, the key is displayed as a black box.


This issue can occur for the following reasons:

  • The key combination is invalid.
  • You move the pointer to the next letter before you release the mouse button.


To resolve this issue, use one of the following methods:

  • Release the mouse button before you move to the next letter or number on the OSK.
  • Click the button to display the key, and then click the same button to select it.
  • Scroll the pointer off the blackened key, and then scroll the pointer back to select the key.
  • Use a valid key combination.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
