Editor & Tabs
Managing editor tabs, split views, and navigation
Tab Management#
Agentastic uses a familiar tab-based interface for managing open files.
Opening Files#
- Click a file in the Navigator to open it
- Double-click to open in a permanent tab (single-click creates a preview tab)
- Press Cmd+P for Quick Open
Tab Navigation#
| Action | Shortcut |
|---|---|
| Next Tab | Cmd+} |
| Previous Tab | Cmd+{ |
| Close Tab | Cmd+W |
| Reopen Closed Tab | Cmd+Shift+T |
Split Views#
Split your editor to view multiple files side by side.
Creating Splits#
| Action | Shortcut |
|---|---|
| Split Side by Side | Cmd+D |
| Split Top and Bottom | Cmd+Shift+D |
The split shortcuts work from files, terminals, browsers, and agent chat interfaces. A terminal split starts a new terminal with the same shell and working directory. You can also:
- Drag a tab to any edge of the editor area
- Right-click a file, terminal, browser, pull request, or chat tab and choose Split Up, Split Down, Split Left, or Split Right to move that tab into a new pane
Navigating Splits#
Move focus between editor panes using keyboard navigation or by clicking in the desired pane.
Editor History#
Navigate through your editing history:
| Action | Shortcut |
|---|---|
| Go Back | Ctrl+- |
| Go Forward | Ctrl+Shift+- |
Jump Bar#
The Jump Bar appears at the top of the editor showing the file path and code structure. Click any segment to navigate.
Toggle the Jump Bar in Settings > General > Show Jump Bar.
Line Operations#
| Action | Shortcut |
|---|---|
| Move Line Up | Option+Up |
| Move Line Down | Option+Down |
| Delete Line | Cmd+Shift+K |
Markdown Preview#
Open any Markdown (.md) file and view it three ways — as Source, as a rendered Preview, or Split with both side by side.
- Cycle the view with Shift+Cmd+V — it steps Source → Preview → Split → Source. The shortcut is customizable in Settings > Keybindings; if you already use that chord for something else, your binding is kept.
- A gentle nudge — a Markdown file opened in Source shows a small "Open Preview" prompt above the status bar with the live shortcut. Dismiss it and it stays dismissed.
- Same modes everywhere — the editor menus, the Inspector, and the prompt all drive the same view, and your choice is remembered.
Set the default mode for newly opened Markdown files under Settings > Text Editing > Markdown View.
The rendered preview uses a calmer, note-focused style: a centered reading column, the system proportional font for prose, guaranteed fixed-pitch fonts for inline and fenced code, and a copy button that appears when you hover a code block.
