First, if you mean you want the tooltip to show a different address, then I
don't think that it's possible.
Second, if you meant you want to see something in the cell that isn't the
address of the link, then...
There's an =hyperlink() worksheet function that may do exactly what you want:
=hyperlink("
http://www.microsoft.com","Click me!")
Third, If you want to use the Insert|Hyperlink style of hyperlink:
I didn't test this in xl2007, but it seemed to work fine in xl2003:
Option Explicit
Function myHyperLink()
With Application.Caller
.Parent.Hyperlinks.Add Anchor:=.Cells, _
Address:="
http://www.microsoft.com"
End With
myHyperLink = "Click me!"
End Function
If you're new to macros:
Debra Dalgleish has some notes how to implement macros here:
http://www.contextures.com/xlvba01.html
David McRitchie has an intro to macros:
http://www.mvps.org/dmcritchie/excel/getstarted.htm
Ron de Bruin's intro to macros:
http://www.rondebruin.nl/code.htm
(General, Regular and Standard modules all describe the same thing.)
Short course:
Open your workbook.
Hit alt-f11 to get to the VBE (where macros/UDF's live)
hit ctrl-R to view the project explorer
Find your workbook.
should look like: VBAProject (yourfilename.xls)
right click on the project name
Insert, then Module
You should see the code window pop up on the right hand side
Paste the code in there.
Now go back to excel.
Into a test cell and type:
=myHyperLink()
