Tooltip button

Plese how to create simple tool tio button.

E.g.
On rollOver display text “Go Home”
RollOut will text not visible.

I tried it, but:

How can i 100% make safe that this action is on for rollOver?

What happens i user make dragOver, releaseOutside, etc.

How should i write conditon for this effect to have only rollOver action for the tooltip?

I can do it somehow, maybe u have simplier solution.
