Verb: to call for someone's attention, especially in an online chatroom (originally used in IRC, where mentioning a user's nickname would cause the message to be highlighted on their screen, accompanied by a sound)
Noun: an instance of such a calling for attention.
You could have asked: is there a reason this easy patch was not applied, either on IRC or private mail by me. You did write a comment on IRC and I did see it. Problem is that you did not highlight me _and_ you did not wait for an answer. *(actual example from linux.debian.maint.boot via Wiktionary)*

Feel free to highlight me or anyone else for a chat.

Stop highlighting me, we've been through this.

I didn't see your highlight. *(noun)*
