Comment 4 for bug 37473

F8 is "Move files" in my Konqueror.

And this bug report *is* the documentation for the feature. (The most easily available documentation, anyway.) I couldn't find it and the documentation search feature didn't work, so I searched Google and found this.

I suppose what I've learned from this is that I should compare the menus in Kubuntu applications to the ones on my Fedora box to find out whether I'm missing something important.
