Menu Options

Option	Description
Undo	Undo the last change
Redo	Redo the last undone change
Reorder Module	Reorganize notes in the current module
Save Module	Export the current module as JSON
Load Module	Import a module from file or reset to default

Undo/Redo

• Undo (Ctrl/Cmd + Z): Reverts the most recent change

• History limit: Up to 50 states are remembered

Save Module

1. Click Save Module
2. A JSON file downloads to your computer
3. The filename includes a timestamp

Load Module

Opens a submenu with options:

Option	Description
Load from file	Opens a file picker to select a JSON module
Reset to Default Module	Loads the built-in default composition

WARNING

Loading a module replaces the current workspace content. Save your work first if needed!

Lock Button

The lock icon toggles note editing:

• Unlocked (🔓): Notes can be moved, resized, and edited
• Locked (🔒): Notes are view-only; prevents accidental changes

This is useful when:

• Presenting a composition
• Exploring without making changes
• Preventing accidental modifications to a finished piece

Footer Links

At the bottom of the menu:

Link	Destination
Documentation	Full documentation site (docs.rmt.world)
Donate	Support the project (Stripe)
License	View the RMT-PNC license

Keyboard Shortcuts

These shortcuts work anywhere in the app:

Shortcut	Action
Ctrl/Cmd + Z	Undo
Ctrl/Cmd + Y	Redo

Tips

1. Use keyboard shortcuts for undo/redo - it's faster than opening the menu
2. Save frequently - there's no auto-save to the server
3. Enable tracking for long compositions you want to follow during playback
4. Lock when presenting to avoid accidental edits during demonstrations
