My Vimium Key Bindings (Emacs-Style)

This is a full set of key bindings (as of Vimium v1.45); covering all Vimium functionality. I have tried to map all Vimium functionality to comparable Emacs functionality (whenever possible). In cases where there is no equivalent, those commands are prefixed by <c-g> (indicating <c-g>oogle Chrome; and because <c-g> does not conflict with other Emacs shortcuts at all).

Commented Shortcuts: There are a few Emacs-style shortcuts that are simply not possible in Vimium. All of my shortcuts (including those which were not possible; i.e. where I used a decent alternative) have been commented below. This should help to clarify my rationale.

_Compatibility: All of these shortcuts were tested on Mac OS X (Mavericks). Please note that all of my shortcuts operate under the assumption that your Emacs Meta key is the ⌥ Alt/Option key. This really was my only choice, because the ⌘ key is already used in Chrome for shortcuts that c

Using Dropbox to Share Git Repositories

First, create a Git subfolder inside your Dropbox folder. Then you can share the individual projects inside that folder with whomever you want (or just use it for instant offsite backups).

From inside a Git project:

git clone --bare . ~/Dropbox/Git/gitproject.git
git remote add dropbox ~/Dropbox/Git/gitproject.git

When you're ready to push:
