+# WeeChat Triggers

+## msgid visibility
+
+```
+/trigger add msgid print "" "${tg_tag_irc_msgid}" "" "/print -buffer ${buffer.full_name} [msgid: ${tg_tag_irc_msgid} ]
+```
+
+This adds a `[msgid: <message ID> ]` below all messages, which can then be entered
+to Ergo's `/msg HistServ delete`.
+
+I improved this from `FiskFan1999` who had a `${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.
