Menu navigation keys and Help text

Actual key behaviour:

F2 Setup menu

CRSR left: exits Setup root menu after releasing both CRSR and SHIFT key. (of course this is not possible in the Setup sub menus because CRSR left is used for changing options)

INST/DEL: go back one menu level. Exits Setup menu if in Setup root menu. This essential key is not documented on the Help page.

F5 Action menu

CRSR left: exits the Action menu. (It is not required here to release the keys like in Setup menu. This could cause to rush all the way up to the Interface root menu if keeping the keys pressed.)

Would be more consistent if INST/DEL could work here too.

General: RUN/STOP: exits Setup or Action menu going back to file browser. Exits the Interface menu if in file browser. F8 (Shift+F7): acts like RUN/STOP (little bit wasted)

F3 Help page

There's no indication that the Help text continues below and that you can scroll the text using CRSR down/up. At least you might see that F1/F7 will do. ;) Pressing F3 again to close the Help page.

Modification ideas:

Making the Help page accessible from any menu.
Also accessing the Setup/Action menu from anywhere (w/o the need to back out a menu first using RUN/STOP).
Additional keys like the striking left-arrow to go one menu step back or the up-arrow to jump to the first entry in a directory. Figured out that * is HOME/POS1.

(Maybe a poll on facebook could show if the user base would accept such changes to the menu navigation... if you consider something like that at all of course.)

F-key layout suggestion (as brainstormed on facebook):

F1: Help F2: Enter Setup menu and cycle through Setup/Action menu F3: Enter Setup menu F4: e.g. "Enter Audio Mixer menu" F5: Enter Action menu F6: ? Show debug log (it's commented out) e.g. "C64 and Cartridge Settings menu" or "Reboot C64" F7: Selection Page down F8: Selection Page up

(* Making F2 / F4 / F6 maybe freely assignable to a Setup sub menu or Action would be awesome.)

Help text page draft, added INST/DEL, Asterisk and stuff (it could even use a bit more tuning maybe :) )
