Cmnd+D doesn't work in a browser - keylogger?

Whenever I’m in Firefox (or Safari, Chrome, etc.), typing Cmnd+‘D’ to bookmark a page flashes the “Bookmark” in the menubar… but doesn't save the bookmark.  I have to type it twice for it to work and I wonder if a key-logger is at work, and how would I find out.  Suggestions?

iMac, OS X 10.11
