Then paste it into another program. For example, Slack or a Google Spreadsheet, or Superhuman, or another place that does rich-text formatting of the pasted text.

### Outcome

#### What did you expect?

I expected the text to be pasted as regular text, like this:


#### What happened instead?

The single line of copied text gets turned in to several numbered points:
