Just a few days ago, both my Ctrl keys seem to have suddenly stopped working for some reason. It's proving to be quite the hassle for as a digital artist, I use a lot of shortcut keys, majority of which consist of the Ctrl key. A couple of days before the Ctrl keys stopped working, the A key stopped working. I didn't seem to be the keyboard so I tried restarting my computer and it started working again. Restarting my computer doesn't unfortunately help my Ctrl keys. Any help I could recieve would be most appreciated.
