Shortcut Review for build and goto declaration

[basarat]

Atom defaults:

ctrl+b : find in buffer
ctrl+shift+b: find modified file

Although I like what I have. I don't feel right in:

a. competing with default shortcuts
b. I find ctrl+shift+b to be difficult to override, in that atom has it hooked very deeply.

So: find other defaults

Suggestion for "Goto Declaration": F12. It's what Visual Studio uses, and doesn't seem to be in use in Atom by default.

Suggestion for Build : F6 Its what visual studio uses
