Notes
Canvas shortcuts only: Formatting shortcuts (Cmd+B, Cmd+I, etc.) and markdown-style shortcuts only work within the Canvas editor panel. They do not affect the main chat input area, which uses a plain text field.
Mobile: Keyboard shortcuts are not available on mobile devices. On mobile, formatting is accessed through toolbar icons and touch gestures within the Canvas editor.
Platform differences: On some Linux distributions, Ctrl+Shift+Z for Redo may conflict with system-level shortcuts. If Redo doesn’t work, try Ctrl+Y instead.
The most useful shortcut for workflow speed: Cmd/Ctrl+Shift+O to open a new chat instantly from anywhere in ZeroTwo, without navigating back to the home screen.
Coming Soon
Additional shortcuts may be added in future ZeroTwo releases. Check this page or follow @ZeroTwo on social media for updates.
