DM42/Free 42 feature request: "User mode"

I miss the "User mode" of the HP 41 on the HP 42S / DM42.

I am referring to the possibility of assigning a program to any key on the calculator and so have a full customized keyboard.

I think that the custom menu feature is a poor substitute. Any possibility that it can be implemented?

HP-41-style USER mode is on my list of "low priority, not sure if I'll even do them or not" items.

In Free42, you can customize the keyboard using custom skins. Of course this is less flexible than true USER mode, and it doesn't help if you're using the DM42.

I miss User Mode too. It's been a fundamental part of my "workflow" since my first HP41.

Free42/DM42 is in many ways a huge step forward from the '41, but the '41 is currently the most effective tool for many of the jobs I deal with on a daily basis. User Mode, and especially the ability to re-assign keys from within a program using PASN, is the reason I still use my DM41x for work, while the DM42 gathers dust.

This isn't just nostalgia, or a reluctance to spend time adapting '41 programs to run on DM42/Free42. The number of keystrokes needed to achieve a task is an objective measure of the efficiency of a UI, and I can find no way to work as quickly and efficiently on the '42. I'll keep trying, though...

User mode would be very nice to have, though there is of course the question of how it would be activated on the DM42 keyboard, since it obviously can't be rearranged to accommodate an extra key. Maybe the F3 key when there is no menu open? That's the only thing I see that currently isn't mapped to any function. And it would be great if it had the 1USR mode like the 48, where only the next keystroke is taken from the user definitions. Maybe press the key once for 1USR, then again to lock in USR mode until it's pressed a third time to deactivate.

And a fourth time to deactivate it only for the next keystroke... :lol:

With the CUSTOM menus, the 42 has a similarly powerful, in some points even better system for quick access to task-related key assignments. You can use it to configure special hot keys for each area of application. I'm curious what kind of problem that could be where the custom keys of the 42 are insufficient. Personally, I can't think of any practical application at the moment in which the CST functions of the 42 would not be sufficient. Even if this exists, it should not be a problem for these few users, who have this kind og problem, to see the 41er as the more suitable pocket calculator in this case.
