The "goto line" feature on most Mac text editors is Cmd+L. And it's consistent.

On the Mac the Control shortcuts are used for text manipulation everywhere and they come from Emacs: C-a, C-e, C-f, C-b, C-k, etc. The Cmd key is not the standard for text editing; it is the standard for all app-specific commands. For example Cmd+I usually makes text italic in a word processor, but in a non-word processor app italic makes no sense, so for example in Finder it means bring up the inspector.
