Mapping the Delete key in Remote Desktop Client for Mac OSX  

I have a ibook and when I am using Remote Desktop Client (in a Windows
session) and I hit the Delete key, it isn?t really the delete key in
the Windows world.  Windows wants the little delete key that in above
the arrow keys on extended keyboards.

How can I make the iBooks delete key may to the Windows Delete key. 
Now it maps to the backspace key, which does ?go back? not Delete (in
many apps).

thanx in advnce,
