# Windows stuck in control mode (Tobias Wulf,windows bug)
Recovery: Most of the time, Ctrl + Alt + Del re-sets key status
to normal if this is happening. (Then press Esc to exit system screen.)
Another method: You can also press stuck key: so if you clearly see that
it is Ctrl which got stuck, press and release both left and right Ctrl .
# Why I have to press keys two times to get the ^ or ´ or ` (windows bug)
With this keyboard layout the ^ keystroke becomes a modifier to
enabling entering of special characters.
To get a single ^ character you will need to type ^+Space.
