Chord Song
Vim-like <Leader> key implementation for Blender that triggers operators, executes scripts, and modifies properties using key sequences. Inspired by Neovim addon which-key.nvim.
Detailed documentation https://furash.github.io/chordsong/
Features:
- Leader Key System — Single-tap to start chords, double-tap for recents, triple-tap to repeat
- Context Menu Integration — Right-click any UI element to add mappings instantly
- Context Awareness — Mappings filter by active editor (3D View, UV, Shader Editor, etc.)
- Four Mapping Types — Operators, Properties, Toggles, and Custom Python Scripts
- Conflict Detection — Built-in checker to identify and resolve mapping conflicts
- Visual Overlay — Dynamic overlay shows available chords as you type
- Groups & Organization — Organize mappings into groups for better overlay structure
⚠️ WARNING: For Developers Only
This addon allows execution of arbitrary Python scripts through custom mappings. This is a powerful feature intended for developers who understand the security implications.
DO NOT execute any Python scripts unless you:
- Wrote the script yourself, OR
- Have thoroughly reviewed and understand what the script does
Executing untrusted scripts can lead to data loss, system compromise, or other serious security issues. Only use scripts from trusted sources that you have personally audited.
What's New
1.2.3 April 23rd, 2026
Overlay: click feature
- Click a toggle to flip it. Overlay stays open so you can chain several without re-opening.
- Click a script to run it. Ctrl-click runs it and keeps the overlay open.
- Hover highlights the script you're about to click.
Better error messages
Unknown operators, missing scripts, bad mapping paths, and scripts outside the configured folder now show clear errors in the Info panel and as a fading overlay.
Security
- The Allow Custom User Scripts toggle is user-only: shared configs can no longer silently enable it. Your setting persists across Blender restarts and addon reloads.
- When a scripts folder is set, executions outside that folder are blocked.
This extension is ridiculously good. Like Quick Favorites on PEDs ... then some!
For those who are into VIM/Neovim, this feels very familiar and makes great sense, given that Blender, being a modal editor for 2D/3D, shares many principles with VIM and its modes for editing text.
Not only does it provide convenient methods for retrieving operators and bind them to chords (sequential key chains), it enables you to run scripts from a personal snippets folder. This opens up a whole new dimension! Yes, numerous tools already did this for ages, but I think this extension provides the quickest experience, thanks to its chorded keys, but also because you can set the context (mode) for things to be effective or not, e.g. only in 3D View, Edit mode, Object mode, Node editors, ...
Fantastic job, Cyrill. Very thankful for your contribution of this speedup tool.
