Perhaps we should change this shortcut to Ctrl+J? I mean, I've heard that it's hard to access Fn keys in Mac, so it could be worth considering this too.

What do you think?

[mrclary]

My personal opinion is that "F3" is fine for a few reasons. We already use function keys for several things and macOS allows users to configure their function keys to be default. Most users were already using "F3" for "find next" which is a more utilized operation than "go to definition", so it won't be any less convenient, I think. Nevertheless, I usually use the "⌘+click" for "go to definition" anyway; I don't know how many users use that vs "⌘+G". I think the biggest pressure point, by far, for changing "find next" and "find previous" is simply consistency with most macOS applications, and not the convenience of the function key.

However, I don't use the plots pane for any of my workflows, so "F3" vs. "⌘+J" will have no real impact for me.

I'll let you make the call.

Ok, I don't have a strong opinion either, so let's leave it like this and see what users think about it.
