Agree this is a very nice and useful extension of the 31S feature set, which would probably broaden it's appeal extensively! Technical MoHPC forum members likely aren't as excited about this feature, but I think we all would like to broaden the appeal of the 31S to a larger audience, and this could be a key way to achieve that.

Of course the obvious obstacle is the key layout, since the N/%/PV/PMT/FV need (IMHO) to be on/near the top row, and lord knows we don't want to revisit that issue, however I hope/suspect this could be accomplished wihtout major rework as follows:

• Have a global setting (Catalog?) enable the TVM suite
• Have 2 sets of Keyboard overlays available
• Technical users keep existing overlay for scientific/engineering use
• A new Overlay with the top keys "labeled" for the TVM functions
• A user desiring primary TVM use gets 2nd overley and enables feature during initial use
• All functions (e.g. the non-current top-row functions) are available via Catalogs
  

Pauli / Walter: Is this approach feasible?
Others: Do you agree this would be a useful extension of the 31S feature set, which would broaden appeal and add useful features?
