fmux

Function-key enabled terminal MUltipleXer enhancements

This project implements byobu-like function key bindings for common tmux commands, but without as much overhead as byobu. It also adds some useful status-bar widgets on the right, implemented with a bash script.

Key bindings

Function keys

These keys work without the tmux prefix (Ctrl-B by default).

F2: New window
F3: Previous window
F4: Next window
F6: Detach session
Ctrl-F6: Kill pane
F7: Copy mode
F8: Rename window
Ctrl-F8: Rename session
Shift-F12: Toggle bindings on/off
Alt+arrow keys can be used to switch between panes.

With tmux prefix

|: Split window horizontally
-: Split window vertically
Shift-W/A/S/D: Resize current pane
r: Reload config from ~/.tmux.conf
Alt-Left or Right arrows: Move window left or right, repsectively

In case any of these bindings interfere with other commands, they can be temporarily toggled on or off with Shfit-F12.

Local configuration options

This configuration file sources ~/.tmux-local.conf if you want to make additional modifications.

Installation

Clone this repository to your home folder.
Establish a symbolic link from the tmux.conf file in the repository folder your home folder: ln -s /home/$USER/fmux/tmux.conf /home/$USER/.tmux.conf

If your tmux version is 2.9 or below, use tmux-2.9.conf instead. Version 3.0 introduced several changes in configuration file parsing. (tmux 2.9 also introduced some changes to the style formatting, but they do not break functionality. I do hope to fix this soon.)
Run touch ~/.tmux-local.conf.
Start a new tmux session, or reload the configuration file in existing session(s).
