Definition: `.tmux.dev.conf` refers to a configuration file that controls various aspects of terminal sessions in macOS, Linux (including Debian), and macOS X. The file configures the application to use the "terminal" session as its default session when it is launched from `/Applications/X11application.tty`, which allows for smoother interaction with the terminal interface. Here are some key definitions: - `.tmux.dev.conf`: This file is named after the domain name, `.tmux.dev`, and contains configuration settings specific to macOS X terminals. It includes various options like: - `autostart`: Enables or disables automatic startup. - `idle_timeout`: Sets maximum number of idle session seconds before termination. - `maximize_mode`: Controls mode for maximized window in the terminal application. - `.tmux.dev.conf.example`: This is a snippet of configuration that demonstrates how to use the ".tmux.dev" domain by creating two sessions, one for a minimised window and one for a full-sized window.
