This release adds command mode for cell navigation and a redesigned data editor. It also includes a breaking change to keyboard shortcuts. See full release notes below.

✨ Highlights

⌨️ Command mode

Many of you have told us that command mode was the one feature you missed most from Jupyter. We heard you, and we've built it into marimo.

Command mode lets you work at the cell level — navigating between cells, creating new ones, and applying operations to multiple cells at once. Press Escape to enter command mode (the cell border turns blue), and press Enter to return to edit mode.

Navigation and cell management: - ↓/↑ - Move between cells - Enter - Edit the selected cell - a/b - Add a new cell above/below - c/v - Copy and paste cells - s - Save notebook - Ctrl/Cmd + ↑/↓ - Jump to top/bottom of notebook - Shift + Enter - Run cell and advance to next

Multi-cell selection: - Shift + ↑/↓ - Select multiple cells - Apply operations to all selected cells at once (hide, delete, disable, etc.)

For vim users: When vim keybindings are enabled, command mode feels natural with familiar navigation: - j/k - Move down/up - gg/G - Jump to first/last cell - Shift + j/k - Extend selection

📊 Revamped data editor

The data editor plugin (mo.ui.data_editor and mo.ui.dataframe) has been totally upgraded.

Direct editing: - Paste from clipboard - Copy data from Excel or other sources and paste into cells - Column operations - Add, rename, or delete columns - Row deletion - Remove rows - No more limits - The 1000-row restriction is gone

Transformations: - Null value filtering - Filter by null/non-null values - Duplicate handling - Remove duplicates with control over which records to keep - Live updates - See changes as you edit - Improved performance - Upgraded grid engine handles large datasets

These improvements make the data editor feel more like a spreadsheet when you need it, while maintaining dataframe operations.

🚨 Breaking changes

• Remove Alt-` for completions (#5609)

Why this change: The Alt + ` shortcut for triggering code completions conflicted with system shortcuts on several platforms, particularly on macOS where it's used for window switching. This caused frustration for users who couldn't access completions reliably.

What to use instead: Code completions now work automatically as you type, providing a smoother experience. If you need to manually trigger completions, use Ctrl + Space (or Cmd + Space on macOS if not reserved by Spotlight), which is the standard shortcut across most code editors.
