# WeeChat Triggers - [WeeChat Trigger plugin documentation](https://weechat.org/files/doc/stable/weechat_user.en.html#trigger) - [Triggers at WeeChat GitHub Wiki](https://github.com/weechat/weechat/wiki/Triggers) ## msgid visibility ``` /trigger add msgid print "" "${tg_tag_irc_msgid}" "" "/print -buffer ${buffer.full_name} [msgid: ${tg_tag_irc_msgid} ] ``` This adds a `[msgid: ]` below all messages, which can then be entered to Ergo's `/msg HistServ delete`. I improved this from `FiskFan1999` who had a `${channel}` instead of `${buffer.full_name}` which was suggested by `trygveaa` on `#weechat` at LiberaChat, after I figured out `${server}.${channel}` which was improper. I also added spaces to the last part.
