I would have given you the keyboard shortcut, however I'm on Linux and not sure if it is different for Windows (you can try it though. To toggle RDV on/off, I press Ctrl + Shift + M)

Thanks for your quick response, Moses! (Less than 1 hr., I think.

And for people who are freaked by the same problem on Windows, the keyboard combination is the same as the one Moses posted for Linux.

Thanks!
