@marijn I got it working so the mark is not applied to the new text! It’s your implementation exactly, except for the second last line

```auto
function markInputRule(regexp, markType, getAttrs) {
  return new InputRule(regexp, (state, match, start, end) => {
    let attrs = getAttrs instanceof Function ? getAttrs(match) : getAttrs
    let tr = state.tr
    if (match[1]) {
      let textStart = start + match[0].indexOf(match[1])
      let textEnd = textStart + match[1].length
      if (textEnd < end) tr.delete(textEnd, end)
      if (textStart > start) tr.delete(start, textStart)
      end = start + match[1].length
    }
    tr.addMark(start, end, markType.create(attrs))
    tr.removeStoredMark(markType) // Do not continue with mark.
    return tr
  })
}

```
