Hello, I'm having similar issues. Mine centers on the "x" key. It works fine when im on a text editor or search box but it will not work when re-naming folders, using the "cut" shotcut (ctrl+x). I also notices that when using the left ctrl button the sound gets muted/un-muted. I've checked the keyboard configs in control panel but I can't find the settings specific to my problem. It's getting really annoying.
