The EDIT function is assigned to down-arrow, and edits the contents of
whatever is on top of the stack. After trying a 48G in emulation,
that's the same behavior as the EDIT key (which was assigned to
left-shifted change-sign). EDIT and VISIT are also in the CATalog, and
naturally can be assigned to any keystroke.

If you want to edit what's STORED in a object whose NAME (within single
quotes) is on the stack, you could write a tiny program: << DUP RCL EDIT
STO >> and assign THAT to a key...

Of course there's such a list. Try http://www.hpcalc.org (it's in the
Emacs package among other places) Lots of tutorials there, too.

I have to agree -- I use CST much more often than MODE, although I can
see HP's reasoning; MODE is more necessary when learning what the
calculator can do after first opening the box... I suggest reading the
manual to see how ASSIGN works, which will allow you to swap the
functions around however you like. (By "the manual" I mean the HP-50G
User's Guide, found on HP's web site and hpcalc.org, not the little
manual that came with the calc.) Please also note that your can create
a program to put in a object called STARTUP in your home directory that
always runs on after resets, and that program can turn your USER
keyboard on so you don't have to remember to do that after reseting.
USER keys on is flag -62, so your STARTUP program could be: << -62 SF >>

Also you may want to look at a package called KeyMan. By adding "long
presses" to the keystrokes, you could assign even more options to a
given key. I have trouble remembering a dozen different things that one
key can do, so I don't use it, but you might like it. As it is, I have
several keys overloaded with shift-hold combos. For instance, UnitMan's
menu is on right-shift-hold 6, and UTool is on left-shift-hold 6.
UnitMan and UTool are both on hpcalc.org.

Sorry, can't help you there! ;)
