This command in the contextual menu is one of the most useful of all. But until recently, I kept forgetting to use it, even though I occasionally noticed Bill referring to it. I think one reason is the name of the command. After all, if I couldn’t see the text, how could I have selected it?
I imagine that it’s an abbreviated form of “See the selected text or similar in other documents”. It’s difficult to come up with something that’s clear and short, but my suggestion would be to use “Explore”.
