We haven't tried this before, and it seems reasonable to me to try. A couple of thoughts:

• Maybe shift-click or alt/option-click, rather than control-click specifically? At least on OSX, control-click already opens a context menu.
• I think the lexer is still going to have to be good enough to split words up. For example, if class::method parses as a single token, I don't think we can easily tell whether the user clicked the "class" word or the "method" word. Splitting words is an easier problem, but it's possible it isn't much easier and that the existing Pygments lexers aren't very good at it.

Or everyone could switch to PHP, a robust language which is amenable to static analysis.

ctrl is what every IDE I've ever used (Windows/Linux) uses, so I'm trying to keep this convention. It's probably the apple key on a mac?

Using command on Macs is fine.

Memo to self: update docs.

Discoverability is a problem now, and the best idea so far is add a note somewhere.

@chad - can you help suggest a way to put a note / anything better?

Additional memo: crtl+click doesn't work. One should press control first and move mouse outside/inside.

Note idea: very transparent grey color note to the top right corner of the first diff ' ctrl+click for lookup ' - short so not very annoying.
