Check out the docs for OpCmd. The procedure that you're wanting is
"AddCommand". In my example below, I've set up a multiple choice list
that "remaps" the key to toggle (like the ) and use
to accept the choices. Here's my example:
{DON'T FORGET TO "USE" OpCmd}
uses
OpCmd; {among others}
procedure GetPicks;
var
PL :PickList;
PickDone :boolean;
begin
if not PL.InitDeluxe(screenwidth shr 1-16,5,
screenwidth shr 1+15,screenheight-6,
AltMenuCS, {color set}
WinOpts, {window options}
33, {width of pick list strings}
NumItems, {number of items}
UserStrings, {user-string proc}
PickVertical, {pick direction-type}
MultipleChoice,{single or multiple}
pkStick)then {stick at edges}
begin
{error message}
exit;
end;
PickCommands.AddCommand(ccToggle,1,$1C0D,0); {Enter=Toggle}
PickCommands.AddCommand(ccSelect,1,$4400,0); {F10=Accept}
PickDone:=false;
repeat
PL.Process;
case PL.GetLastCommand of
ccSelect: {F10}
begin
end;
ccQuit:
PickDone:=true;
ccError:
begin
PickDone:=true;
end;
end; {case}
until PickDone;
HideMouse;
{NOTE THE FOLLOWING LINES: They're needed to remap the
key to its original setting and gets rid of the key as
the ccSelect. If you want *ALL* of your pick lists throughout
your program to behave this way, use the PickCommands.AddCommand
at the beginning of your program.}
PickCommands.AddCommand(ccSelect,1,$1C0D,0); {Enter=Toggle}
PickCommands.AddCommand(ccNone,1,$4400,0); {F10=Accept}
PL.Done;
end;
end;

You'll have to use the "AddCommand" method. Here's an example. This is
based on "expick1.pas" from Page 4-186 of Book #1.
}
program PickListExample;
uses
OpCrt, OpRoot, OpCCmd, OpFrame, OpWindow, OpPick;
const
NumPizzaToppings = 5;
var
PizzaTop : PickList;
PickWindowOptions : Longint;
procedure PizzaTopping(Item : Word { etc... }) : Far;
begin
end;
begin { Main }
if not PizzaTop.InitCustom(35, 5, 45, { etc ... }) then begin
halt;
end;
PizzaTop.SetSearchMode(PicckCharSearch);
PizzaTop.EnableExplosion(20);
with PizzaTop.wFrame do begin
AddShadow...
AddHeader...
end;

{ the "AddCommand" method! }

end;
PizzaTop.Process;
PizzaTop.Erase;
case PizzaTop.GetLastCommand of
ccUser1 : ; { If User hits INS, this is executed }
ccUser2 : ; { If User hits DEL, this is executed }
ccSelect : writeln('You chose : ',PizzaTop.GetLastChoiceString);
end;
PizzaTop.Done;
end. { Main }

Nick--The manual does go into subtantial detail. You just need to
know where to look. As with much of OPro, the things you want to
do with a particular object may be implemented, not in the object
per se, but in one of its ancestors. It always pays to look in the
manual at the ancestor's methods.
You need to read up on CommandWindow, from which PickList is
descended, and on CommandProcessor, in OpCmd. Here's a relevant
piece of code from one of my programs. The first AddCommand adds
an additional Quit; the others are for purposes specific to my
application, not for predefined commands such as ccQuit.
}
with DialPickList { a PickList descendent } do
with PickCommands do begin
{ Simulate WordPerfect's exit command }
AddCommand(ccQuit,1,$4100,0); { F7 }
{ ccUser0 = Add a new phone entry }
AddCommand(ccUser0,1,$1E00,0); {Alt-A}
AddCommand(ccUser0,1,$5200,0); {Ins}
{ ccUser1 = Delete a phone entry }
AddCommand(ccUser1,1,$2000,0); {Alt-D}
AddCommand(ccUser1,1,$5300,0); {Del}
{ ccUser2 = Edit a phone entry }
AddCommand(ccUser2,1,$1200,0); {Alt-E}
{ ccUser3 = Reconfigure Comm Stuff }
AddCommand(ccUser3,1,$2E00,0); {Alt-C}
{ ccUser4 = View log (the printing and purging routines branch
from the browsing routine }
AddCommand(ccUser4,1,$2F00,0); {Alt-V}
end; { with PickCommands }
end; { with DialPickList }
