I haven’t found an open feature request. But I found this open plugin idea. Delete matching bracket/link to easily remove link?
Also there is this help thread which suggests the “Text Format” plugin, which does have a command for removing links. I’ve never tried the plugin myself:
Remove WikiLinks format in selectionRemove URL links format in selectionConvert URL links to WikiLinks in selection
But in terms of typoing to the wrong note, this wouldn’t change the name. It would remove the brackets (I guess), and leave the incorrect name. In which case, you might actually be wishing for a way to quickly edit the text inside a link?
