Basic questions about HP-41c

[pascal_meheut]

Hi, I've had HP-41C and accessories for a long time but never really bonded with them.
Now, they are starting to grow on me and I would like to do something simple but I'm not quite sure on how to proceed.

I will write several small programs and assign them to keys. I wouid like to save my programs and key assignments on one card (they are short enough).
How can I do it?

Also, can a program assign user keys?

And finally, is there a way to use the wand to read both a program and key assigments?
