Goto Keybind Suggestion

[Remillard]

In Emacs, Goto Line is actually M-g M-g and in EPE it's just a single M-g. If you do it as a couple, of keybinds, then it actually opens up room for adding binds to the other more specific Sublime goto commands. I haven't decided what makes sense, but could keep M-g M-g for Goto LIne, but then M-g M-s for Goto Symbol and maybe M-g M-p for Goto Symbol in Project, M-g M-d for Goto Definition (and so forth -- I haven't tested these keybinds to see if they feel good at all.)

Secondly, do you all accept simple pull requests? Now that I'm more familiar with Git, GitHub, etc, I feel like I could make a couple of the changes (like the undo command keybind and these) and send a pull request for consideration. But if it's desireable for it to be all core crew work, then I won't worry about it too much.
