Plus42 Equations, Preview Release

I'm thinking along these lines for how to use the second row:

Code:

 DIR.FCN UNIT.FCN   SST↑     NSTK
[ DIRS ] [ UNITS] [ XSTR ] [  R↓n ] [  EQN ] [      ]

These are just my personal favorites, but anything is possible. A TVM menu might be nice, although I'll have to write some new code to make that usable (the TVM functions I wrote for use in equations aren't really usable in RPN mode, and even there, only in NSTK mode). And there's a whole key still unused in this scheme.

DIRS and UNITS are the catalogs of the same name, and DIR.FCN and UNIT.FCN are the DIR and UNIT sub-catalogs, with directory- and unit-related utility functions, NSTK will be an NSTK/4STK toggle, and EQN jumps into the equation editor, in SOLVER mode.

The final result will be something close to this, but I am open to suggestions in case I overlooked something important, and of course there's that whole still-unused key, that I don't really have strong feelings about...

What is R↓n ?
I think keys that are available in the 32SII but not directly in the 42S could be useful: X<> (above STO), RUP (above RDN) , %CH (above %), and also direct access to VIEW.
The TOP.FCN menu would become useless and hence reusable for hyperbolics, like you did for the equation mode.
TVM could be one key, that's the only feature missing from the 27S, and in that case not only the TVM equation (easy to reproduce with a Plus42S equation) but also the extras from 17B/27S, BEGIN/END toggle button, and amortization table than can be printed.
Also direct alpha entry by pressing the bottom right corner of the keys, like in the KHOR skin.
And extra labels (in blue) for the Plus42 equations functions in equation mode: = : ( ) { } L() G()
