# Terminal

[Alacritty](https://alacritty.org/) is the default terminal for Omarchy. It's fast, beautiful, and compatible with even old computers. It does not, however, support native tabs, splits, or image rendering. 

If you use Tmux, you may not mind, but if not, we fully support _Ghostty_, _Foot_, and _Kitty_ as options as well. Pick your preference under _Install > Terminal_ in the Omarchy menu.

You start a new terminal using `Super + Return`. (This binding will automatically point to whichever Terminal you've installed via _Install > Terminal_.)

## Tmux

Tmux provides a consistent, programmable interface for panes, windows (aka tabs), and resumable sessions regardless of your terminal. It even works on remote hosts, so when you're SSH'ing into a server, you can use the same approach.

You start a new Tmux session in a fresh terminal using `Super + Alt + Return`, and because Tmux is a persistent process, you can resume your session even if you close that terminal. Just hit `Ctrl + Space` (called the prefix key) then `s` to see all your active sessions.

Omarchy ships with an ergonomically-optimized Tmux configuration, which has a lot of keybindings to learn, so keep [the cheatsheet handy](https://learn.omacom.io/2/the-omarchy-manual/53/hotkeys#tmux).

## Tmux layout functions

Because Tmux is programmable, we can use functions to create layouts. Omarchy ships with three different functions for common developer layouts.

`tdl [agent]` starts a three-way split IDE-like interface with the `$EDITOR` on the left, your chosen AI agent on the right (like `c` for opencode or `cx` for Claude or `codex` for OpenAI), and then a terminal at the bottom. 

So `tdl c` would start this (or just `ic`):

You can also start a second agent with `tdl c cx` (opencode + claude) (or just `icx`):

You can also start this layout configuration for every subdirectory in the current directory using `tdlm [agent]`, then navigate using `alt + 1/2/3/5/6/...`:

Finally, you can start a swarm of agents using `tsl [panes] [command]`. So `tsl 4 c` will give you a four-way grid of opencode agents:
