HP50g: Defining custom user keys that work also in the Equation Writer

[BruceH]

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).

You are NOT alone! ;-)
