TScreenTipsManager shows ribbon bar context sensitive help--how can i make the "Press F1 for more help." show the context sensitive help?

Question

i'm using delphi 2009 with the VCL's TRibbon and TScreenTipsManager.

TScreenTipsManager shows ribbon bar context sensitive help--how can i make the "Press F1 for more help." show the context sensitive help? what i mean is that they're hovering over a certain button, see the hint, and then press F1 for more info on this button...what's the best way to make it so if they indeed press F1 that they get help on the same topic (not the form's help topic)?

thank you!
