WEll you can't block it in the IDE very easily.. but I found that
if I had just this:
on commandKeyDown theKey
switch theKey
case "a"
if the selectedField is not empty then
select text of the selectedField
end if
break
end switch
end commandKeyDown
then cmd-x,c,v (copy, cut, paste) were all blocked...
But this handler may not be doing anything, if it is in the script
for a field, because it duplicates the default behavior.
I think I have figured out for sure (?) that a commandKeyDown handler
in the script for a field will not capture, block, or divert a cmd-A
pressed when that field has the focus. I tried this, so as to make
cmd-A simulate a particular button-press in a context where selecting
all the items in a field did not make any sense.
The only way I could find is to use a rawKeyDown handler, with a test
inside it for "if the commandKey is down", and a switch inside that.
This means that if cmd-A is supposed to do the same thing when the
focus is outside the field, I also need a commandKeyDown handler one
level up, in the card or stack script, which does the same thing.
So commandKeyDown works outside the field, but only rawKeyDown works
inside the field.
I'd really like to know if I've got something wrong about this.
