For the verb form, "mouse" is the verb. You wouldn't say, "You should walkover the grating like Marilyn."

For the adjective form, my general rule is to close it up.

See, I'm with you. I'm revising a document and we don't have a style guide, so it's style-guide-by-consensus time.

I am very undecided.

For verbs, I like either "mouse over" or "mouse-over."

For modifier, I like either "mouse-over" or "mouseover."

I think the main conclusion here is that I really like hyphens.

You fly over the flyover states. The same thing applies here.

I would go with "mouseover" for the adjective were it not for the vowel collision, especially with the silent "e." My brain sees it as some unknown French word, even when I know what it's supposed to be.

For some reason for me, "Mouseover" sounds like it should be some British aristocratic house. ("Lord Tick from the house of Mouseover"). Pronounced with a /z/, of course ;-)

The proper spelling for mouse-over text is Tooltip text.

Since this wasn't listed as an option, but should have been: The little boxes are all made of ticky-tacky, and they all look just the same.
