HP 28S - Custom Menu

[Giuseppe Donnini]

It's actually very straightforward:

1. Build a list with the commands/functions/variables you want.
2. Execute MENU (it's in the MEMORY menu, but on an HP-28 you might as well type it in).

To implement your example, the actual keystrokes would be:

1. {
2. α   (to deactivate immediate-execution mode)
3. SHIFT + 1/x
4. SHIFT + ^
5. SHIFT + √
6. ENTER
7. SHIFT + MEMORY
8. [MENU]
