@halirutan It's my bad because I thought cmd+shift+... was for OS X, and it didn't work, so I added Ctrl+^+6 as an alternative. But then when you told me it was a typo I realized, as you just did, that I'd typed ^ whereas you typed the same thing as shift+6 and so I removed my version from your answer since it is the same if you make that change. The extra 6 in my version comes from ^6 where ctrl+shift+6 creates the box and you have to type 6 again to get ^6.
