Tmux Prefix Mode

Tmux is a terminal multiplexer that lets you switch easily between several programs in one terminal, detach them, etc. It's very useful but most key bindings require a prefix key combination (default: Ctrl+B). This mode allows you to use a simple [ Modifier + Key ] to trigger a [ Ctrl+B ] [ Key ] sequence.

How to use

  • Choose a trigger key to be used
  • Chooose a prefix to replace (based on your tmux configuration, default is Ctrl+B)
  • Now trigger a tmux command simply using Trigger + Key (eg: Fn+c -> Ctrl+b, c to create a new window)

Note: Keys that are remapped include: a-z, 0-9, comma,slash,period,semicolon,quote,open_bracket,close_bracket
