In lots (but not all) UI components, if you hover over them, we popup a help tooltip which shows on delay (you hover over a component for a second and a tooltip pops up).

The problem is - the user doesn't know which component has help text and which doesn't. You are forced to hover over a component and cross your fingers that within a second, a tooltip with help shows up.

We have a new way using FormUtility.addContexualHelp() that adds a help icon to the FormItem and when clicked pops up a help dialog box with the help text.

this is better because the user has immediately feedback as to which form items have help associated with it.

we should consider converting all of our help hovers to this contextual help dialog box with icon, where appropriate.
