It is hidden by default; whichever tab you leave it on is where it opens next time. The three icons at the top switch tabs, and clicking the lit one puts the panel away again. The tty7 side panel ## Info Everything tty7 knows about the focused pane, in one column: | Section | What it shows | | ------------- | --------------------------------------------------------------------------------------------------------------------------------------------- | | **Session** | working directory, shell, SSH connection, git branch, `+N −M` changes, and the coding agent with its status (idle / working / waiting / done) | | **Processes** | the process tree inside the pane, with the foreground process marked | | **Ports** | every port those processes are listening on | Hovering a row shows what it can do at the right-hand end of it: **Copy** on the working directory, the SSH host and the branch, and **Reveal in Finder** / **Open Folder** alongside it on a working directory this machine can see. The `+N −M` counts open the [diff overlay](/git/diffs), the same click the sidebar's counts answer to — and the same **Settings → Window & Tabs → Open diff preview from sidebar counts** turns both of them back into plain text. The ports section is the quickest answer to "what is this pane serving, and where" — the same data `tty7 procs` prints. A port row copies `localhost:PORT`, and on a local pane opens it in your browser. ## Source Control The git panel for the focused pane's repository, in four groups — **Merge Changes**, **Staged Changes**, **Changes**, **Untracked**. Write a message, commit, and push without leaving the window. [Source control →](/git/source-control) ## Files A file tree rooted at the pane's working directory, with git status decorations on every row and a search box at the top. The search box carries a clear button while there is something in it. * **Click a file** to open it in the built-in editor. * **Drag a file out** to Finder or Explorer to copy it there. * **Drag files in** from the desktop to copy them into the folder under the cursor. A folder row takes them itself, a file row stands in for the folder holding it, and the empty space below the tree means the top of it. Folders come in whole, the executable bit survives, and a name that is already taken is asked about rather than replaced. Both directions work over a [remote workspace](/remote/workspaces) too, reading on one machine and writing on the other, up to the size one control frame can carry — past that the panel tells you to use [SFTP](/remote/sftp). ## The editor ⌘ ⇧ E toggles the code panel; clicking a file in the Files tab opens it there. It is a real editor — syntax highlighting, line and column readout, wrap toggle, and a Markdown preview — meant for the edit you would otherwise have opened `vim` for. | | | | -------------- | -------------------- | | ⌘ S | Save | | Esc | Back to the terminal | Files are watched on disk: a change underneath you is picked up, and closing with unsaved edits asks before discarding them. Files over 4 MB and anything that looks binary are refused with a note rather than opened badly. ### Where it opens The editor docks beside the terminal, taking half the space between the sidebar and the right panel. The terminal keeps running, stays visible, and stays typeable — click it, read what your agent said, click back. Diffs open in the same column. Drag the divider for any width between a fifth and four fifths of that space — the range `document_ratio` keeps — or double-click it to cycle a third, a half and two thirds. **Document: Third / Half / Two-Thirds Width** in the command palette do the same. On a narrow window the terminal's own floor stops the divider sooner. Right-click the document's header for **Fill window**, which is the old full-workspace overlay, unchanged. **Document: Fill Window** and **Document: Dock Beside Terminal** in the palette are the same switch. Fill or dock is **per tab**: read a long file over the whole window in one tab while an agent keeps half of another, and neither moves the other. A fresh tab starts from `document_layout` in `config.json`. The width is shared, and persists as `document_ratio`. A window too narrow to give both the terminal and the document a readable width fills for that file only — widen it and the column comes back, without your setting having changed.
