Using Hermann’s post, I’ve made my own tmux config changes.
The most common stuff to change in your tmux.conf file is the prefix key. The default for this is C-b which is odd to type every time you need to send the prefix. I prefer mine to be C-z.
For some reason, the default split screen shortcuts are crazy. Who wants to type C-z " to split vertically and C-z % for horizontal? What? That’s dumb. There’s a simpler way.
Reload the config
Might as well make it easy to reload your tmux config anytime.
Changing the view is a frequent thing you do once you start working in tmux. Why not make it super-fast?
I’m not quite fond of triggering the prefix key all the time. I want to be able to simply say M- to go where I want to go (remember: M is for Meta, which is usually your Alt key). With this modification I can simply press Alt-left to go to the left pane (and other directions respectively)
Make it beautiful
If you’re going to spend time there, it might as well look great.
I really like the color scheme Hermann uses.
Please read Hermann’s post, it really does a great job of explaining the things you need to be aware of.
