How do I reassign a bug to another package in the Debian bug tracker?

How to change the software package an issue is filed under in the Debian bug tracker? The help page has these instructions: > In case you need to write a message to the bug and also manipulate the bug's metadata, the commands can also be included in the mail to nnn@bugs.debian.org. Do this by starting the mail with the commands prefixed by Control: . Another common way is to send a copy of the mail to control@bugs.debian.org and start the mail with commands terminated by thanks. and then under Commands available: >reassign bugnumber package [ version ] I tried: * Control: reassign -1 kde-plasma-desktop [5:142] at the start of mail reply to the bug report with control at bugs.debian.org in the CC (I think I should have used nnn@ here; all below went to the same control email) * Control: reassign 1019438 kde-plasma-desktop [ 5:142 ] * Control: reassign 1019438 src:kde-plasma-desktop [ 5:142 ] (thanks in the line below) * Control: reassign 1019438 kde-plasma-desktop (thanks in the line below) * reassign 1019438 kde-plasma-desktop [ 5:142 ] (thanks in the line below) I could not find a full example anywhere so I'm asking here.
