Along with Spacemacs I work with a tmux session with all my projects opened, usually a single project window consists in at least two panes, one for the server and one for the tests.
In Spacemacs you move to window 2 with SPC-2. It's
pretty useful, especially when you have multiple files opened.
In tmux I used to move around using C-a UP if for example I wanted to go to the pane
above the current one, needless to say this feels awkward when you switch from one program
to the other, so I tweaked the configuration a bit until I got the same behaviour in both.
In my .zshrc
tmux-select-pane-1() { tmux select-pane -t '1' }
zle -N tmux-select-pane-1
bindkey " 1" tmux-select-pane-1So whenever I type SPC-1 in rapid succession I move to pane 1.
To avoid having pane numbers starting from 0 I have this in my .tmux.conf
setw -g pane-base-index 1
I've found it useful to have the pane number in my RPS1, so I know where to switch, use this:
echo $(tmux display-message -p '#P')
You have to be careful when you write a space followed by a number (it happens in my workflow as I use SCM breeze), but it's a minor annoyance and I think over time I'll get used to it.
