The combination of tslime and turbux makes running tests from Vim in a tmux session as easy as a single key binding. One problem that can arise from time to time is having tslime focused on an undesired tmux window/pane combination. There is no binding to tell tslime that you’d like to re-select the target window and pane.

I’ve often resorted to closing out of Vim in order to reset the prompt. There is a better way and it doesn’t require you to wipe out your Vim session.

Just unlet the global Vim variable for the tslime plugin like so:

:unlet g:tslime

The next time you invoke turbux it will see that g:tslime isn’t set and will prompt you for a new window and pane combination.
