what's the equivalent of an Excel comment in Visio?

[rik]

i.e. in Excel a comment 'opens' when the user hovers over the cell. In Visio
it seems only for revision comments and a 'user', for example, viewing the
document as an HTM file in a browser doesn't get to see the comments.

Depends on which version of Visio you have.
In Visio 2003/2007 select the shape and menu Insert -> Shape ScreenTip
In 2002 and before it's menu Insert -> Comment
