HP50g: Defining custom user keys that work also in the Equation Writer
Hey,
I try to implement this User Keyboard Assignment:
switching between:
INV() key:64.10
and
Y key:64.40

It works fine , but not in the Equation Writer and the Matrix Writer.
I tried also with KEYMAN , no luck there also,
Is that possible?

I use:
Hp50g
rom 2.15

Thanks for any help.

I don't think this would work. Those applications have their own key definitions (assuming they were ported over from the HP48 series and not modified).

This old comp.sys.hp48 post from Joe Horn might help:

Quote:To force an HP49 key to "work" even when the command line exists, just
tack a "TakeOver" in front of it. To do that, put the desired key
definition on the stack, make sure library 256 is ATTACHed, and then do
this:

#275C6h A-> SWAP 2 ->PRG

The result will look the same as what you started with, but it will
have an invisible "TakeOver" in front of it. Now when you assign it to
a key, it'll work even in edit mode.

One time that it's essential is when you're editing a program and need
to echo something from the stack into the program. Then pressing HIST
is the only way to start the interactive stack. (On the HP48 it was
done by a menu key, but The Powers That Be decided against that for the
HP49).

> But this is just an example there are several keys I'd like to change

You are NOT alone! ;-)

Unfortunately, neither the EquationWriter nor the MatrixWriter pay any attention to user key assignments, even if they have a TakeOver up front. Bottom line: No, you can't use your key assignments while running those applications.
