You can avoid having lots of macros and just use this one for ALL links:
Code:
Sub gotoALT(oshp As Shape)
On Error Resume Next
SlideShowWindows(1).View.GotoSlide (CLng(oshp.AlternativeText))
End Sub
All you need do then is copy paste the button and change the Alt Text for each shape to the slide needed.
Right Click>Size/Position > Alt Text (use the Description box in 2010)
