How to direct a Comment in a Google Doc to a particular user (who is sharing the Doc)?

Question

Is there an easy way to direct a Comment I make in a Google Doc to a parciular particular person it's shared with?

I.e., I'm sharing MyDoc with 3 people. I have several questions I've entered as Comments. I want to direct those comments to only one person and also have them know that those are directed at them (otherwise we'll have Diffusion of Responsibility and everyone assumes someone else will answer it.)

Answer 1

Ah... figured it out:

If you type @ in the Comments you get a dropdown of your contacts. You can select someone from there. Cool! Note that this is not currently available in Google Spreadsheets.

FYI, there are also Discussions available for documents.
