How to edit PGP key in browser, to change signature to include user's keybase.io link by replacing the existing keybase.io/crypto link

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512

Hello,

I am seeking to change my PGP signature comment, do I have to use the command line or can I use the web browser to edit my PGP signature, to replace the current link [@crypto](https://keybase.io/crypto) to [@julientm](https://keybase.io/julientm) with my profile link.

From **https://keybase.io/crypto** to **https://keybase.io/julientm**

Thank you for the great service!

The issue names no repository file, test, or entry point. Start by checking the browser workflow for editing a PGP signature comment, then document whether the existing keybase.io/crypto link can be replaced with the user's keybase.io/julientm link and what supported steps or limitation apply.
