I'd say that does illustrate why I chose to just get proficient in Vim though. There are enough of these kinds of scenarios where having it available is very useful. But if you don't know Vim, you wouldn't bother learning it for just them.

For example, I couldn't imagine using a browser without Vim keybindings anymore. I wouldn't have learned how to use any kind of shortcut/keyboard-only extension, but since I already used Vim it was a no-brainer.

It's a lot of little benefits here and there, and I think taking a bit of time to get comfortable with it would even benefit no-programmers who do a lot of text editing. Plus geek cred ;).
