This describes the workflow to use Heroku as a staging environment. It assumes you already have an existing heroku app in production.

# rename your git remote heroku to something else like production
git remote rename heroku production

# so now you will push as: git push production master

# create the staging app
heroku apps:create staging-appname

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

I use tmux splits (panes). Inside one of these panes there's a Vim process, and it has its own splits (windows).

In Vim I have key bindings C-h/j/k/l set to switch windows in the given direction. (Vim default mappings for windows switching are the same, but prefixed with C-W.) I'd like to use the same keystrokes for switching tmux panes.

An extra goal that I've solved with a dirty hack is to toggle between last active panes with C-\.

Here's how it should work:
