Thanks - but not really what I'm after (as you pointed out). If
I wanted a command, I wouldn't need bookmarks at all. (Though this is
not an unreasonable thing to use, either.)

Exactly.

That was more or less what I was thinking about. I was just curious
whether Bookmark+ has some UI for that scenario.

And this is probably the cleanest solution, and the one which I'm going
to use.
Thanks!
