# The navigation band & modules

The **navigation band** runs across the top of the window: the Home button, the module bar, the notifications bell and
the Quick Command button. Each module is a different view of the same projects.

## The modules

| Module | macOS | Linux | What it does today |
|---|---|---|---|
| Home | `⌃⌥H` | `Ctrl+Alt+H` | Pages of panels per project, and the copilot. |
| Git | `⌃⌥G` | `Ctrl+Alt+G` | The repository: history, branches, changes, everything in the Git section. |
| IDE | `⌃⌥I` | `Ctrl+Alt+I` | A file explorer and a **read-only** file viewer for the repository, with search. |
| Database | `⌃⌥D` | `Ctrl+Alt+D` | A preview with sample data; it does not connect to a database yet. |
| Agents | `⌃⌥A` | `Ctrl+Alt+A` | The Claude Code agents running on your machine, read only. |
| PM | `⌃⌥M` | `Ctrl+Alt+M` | A preview of a ticket board with sample data; it does not connect to Jira yet. |

`⌃⌥→` and `⌃⌥←` (`Ctrl+Alt+→`, `Ctrl+Alt+←` on Linux) move to the next and the previous module.

**Settings › Modules** shows, hides or turns off each module. Home cannot be turned off.

## Home

Home holds pages of panels you build for each project, and the copilot dock. See [Pages & panels](/docs/home/pages)
and [Copilot](/docs/home/copilot). tratto starts on Home unless **Settings › General** says to reopen the last tab.

## Git

The Git module is the Git client: see the Git section, starting with [History & the graph](/docs/git/history). A
project whose folder is not a repository, or has moved, says so instead.

## IDE

Browse the files of the repository, open them in tabs and search across them (`⇧⌘N` for files, `⇧⌘F` for text, double
`Shift` for everything, on Linux `Ctrl` in place of `⌘`). Files open read only: tratto is not an editor yet.

## Agents

If you run Claude Code, the Agents module shows its sessions and sub-agents, their cost, the worktrees they work in,
and which uncommitted files each one changed. See [Agents](/docs/ai/agents).

## Notifications and Quick Command

The bell (`⌃⌥U` / `Ctrl+Alt+U`) opens what changed on your remotes: see [Notifications](/docs/home/notifications). The
Quick Command button, or `⌘P` / `Ctrl+P`, finds a repository or a command: see [Quick Command](/docs/home/quick-command).

## Menus on Linux

On macOS tratto uses the system menu bar. On Linux it draws its own menu bar in the window, with the same menus.
