That is because some menu items are not scripted, they are built in to
the executable program (i.e. written in C and compiled with the

Yes, it would require a way of choosing where in the menu system to
place the new item. Instead you can put your Scheme script into a
command in the menu system by right-clicking a command in the menu
system and choosing "Save Script as New Menu Item" which will insert
the script in that menu after the menu item you clicked on.

Once it is in the menu system you can set a shortcut as usual.

I think you are muddling up two separate things. One is the commands
themselves which you want to create in the menu system (somewhere under
the Notes/Rests menu) and the other is a command to set all the
shortcuts for that set of menu items - that command I imagine you would
put in the Input->PC keyboard menu.

yes, you would put all your keybinding statements one after the other
in the script that you use to set that "mode". So your command to turn
on the mode would look like this:

(d-AddKeybinding xxx yyy)
(d-AddKeybinding xxx1 yyy1)
(d-AddKeybinding xxx2 yyy2)

Then executing this command (which you will assign some shortcut to
(*)) will switch mode for you.

(*) actually you could be cunning and set a shortcut for the switch-
mode command at the end of your shortcuts for the switch-back-to-
normal-mode command and the same shortcut at the end of the switch-mode 
shortcuts script. In that way with a single shortcut you would toggle
between your modes. It would save having to have one shortcut to switch
into your new mode and a different one to switch back to normal mode.
