Hmm hmm, you can also just use MS Word (I have incidentally just migrated to LibreOffice and it has the exact same search functionality, IDK about other text processors) to search the input for this regexp:
#[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]
Find All and then Copy
This will only find 8-digit IDs but there might actually be a regexp for "any string of digits" that I'm not aware of?
Re: Way to extract a batch of IDs from your AH history.
