"control +a" not working on mac, but "control + e" works Today control+a combination stopped working. So I cannot move cursor to beginning of line in terminal or browser input. 

Although yesterday it was working well. control+e works good.

In eventViewer of KeyRemap4MacBook app I cans see that when I press control+a, control key is logged, but a key not logged.



When I press a key without control it is typed in any application and logged in eventViewer.



Why control+a not working? How to enable it?
The reason was application Music Player for VK Lite. When quit it, control+a start working again.
