Keen 4-5: help menu thing

Well, in Keen 4 & 5, when I press F1 (no matter where I am; in-game or main menu), I immediately go the ComputerWrist help section (so you have no choice to choose between the help sections). And if I wanna go back to the main menu or the game, I can simply do it by pressing ESC in the ComputerWrist help section. Is this patch possible?

A surprisingly tricky thing to figure out. The Keen 4 and Keen 5 patches had to be done rather differently to avoid crashing the game:

Code: Select all

#F1 brings up Computerwrist help only -Keen 4
%patch $9C61 $FF08W
%patch $9B54 $90 $90 $90 $90

#F1 brings up Computerwrist help only -Keen 5
%patch $EBDA $FF03W
%patch $E99E $5F $5E $8B $E5 $5D $CB

DID YOU KNOW: It's possible to scroll Keen's help pages using the PgUp and PgDn keys? I found that out looking at this patch!

@Levellass: the Keen engines are full of surprises, aren't they? I also figured out that scrolling option just a couple of month ago. But I was pretty certain that I must have been the only person who missed it.

Thanks. Now what about the other Keen 5 patches I requested below?
