With the required cell highlighted
Insert - Hyperlink - Screen Tip - <Enter Text to show
Now when you put the cursor over the cell whatever you enter will appear in
a similar manner to a comment.
You can also select a range of cells (on another page ?) to be show by using
the second part of the Hyperlink option

I would like to create / edit a 'tool tip' (little yellow message box like
thing) that occurs when you mouse over a cell in a worksheet.

I have an existing worksheet with this functionality, and would like to
amend it and create new ones and have no idea how. It is not a comment box.

Any Ideas?

Your assistance is appreciated.
