Keybinding Extra

A minimal ComfyUI extension that adds several quality-of-life tools:

• Injects handy keyboard shortcuts into the ComfyUI frontend
• Adds a utility node Text Cleaner & Splitter (v1.02) for text preprocessing

In ComfyUI Settings you can enable/disable shortcuts and customize their behavior.
The utility node can clean text, remove comments, and extract regional prompt tags.

Text Cleaner & Splitter (new in v1.02)

A new node added in category: utils/primitive
Node name: Text Cleaner & Splitter

This node performs two major tasks:

---

1. Text Cleaning (comment removal)

The node removes all comment lines from the input text.
The comment symbol is configurable in ComfyUI Settings (same setting used for CTRL+/).

Output is provided on:

• cleaned_text

---

2. Regional Prompt Tag Extraction

The node supports 5 regional prompt tags, written in uppercase:

<AR1></>
<AR2></>
<AR3></>
<AR4></>
<AR5></>

Each tag can contain multiple lines of text.
Comments inside the tag body are also removed.

The extracted content is returned as a fixed-length List on output:

• ar_list

Properties of ar_list:

• Always has exactly 5 elements
• Order corresponds to AR1 → AR5
• Missing or empty regions return null
• If tags repeat, their contents are concatenated
• Closing tag is always strictly </>
• Newlines inside tags are preserved

Example

Input text:

<AR1> Bla1 bla1 bla1 bla1 bla1 </> 
<AR3> Bla3 bla3 bla3 // Bla3 commented </> 
<AR3> Another bla3 bla3 </>

Output:

[
    "Bla1 bla1 bla1\nbla1 bla1",
    null,
    "Bla3 bla3 bla3\nAnother bla3 bla3",
    null,
    null
]
