Anyway completely forgot that pressing the option key will result in another character than exspected!
This surprises me as well. I would have thought that if you pressed "opt-F", asking for tKey would give you "F". This is the case for both the "commandKeyDown" and "controlKeyDown" actions. The dictionary does not address this well, though it does mention that Mac OS has peculiarities.

On a Mac the Alt/Opt key is a modifier key in the sense the Shift key is a modifier on Linux, Mac, Windows, UNIX, and so on.
As the first 'modern' computer I used (i.e. one where the keyboard had an Alt/Opt key was a Macintosh, I still wonder what role that key plays in other systems.
Does anyone remember 'Key Caps' on MacOS 7, 8, 9, 10, 10.1, & 10.2 ?

Hi Klaus,
I tried putting on the card
Code: Select all
on commandkeydown tKey
switch tKey
if theKey is "1" then
send "mouseup" to btn "radio40"
end if
end switch
end commandkeydown
and
Code: Select all
on commandkeydown tKey
switch tKey
case "1"
send "mouseup" to btn "radio40"
break
send "mouseup" to btn "radio41"
break
end switch
end commandkeydown
I then tried hitting "1" and Alt/"1" to no effect.
I don't really follow the logic of the code being on the card, or how to get it working.
Any further clues please ?

It will work with the correct syntax!
In the first handler there is the CASE missing, so switch will do nothing.
This will do:
Code: Select all
on commandkeydown tKey
switch tKey
case "1"
send "mouseup" to btn 1
break
end switch
end commandkeydown
Although a wrong syntax, the second handler does also work for me!
But I'm on a Mac, maybe that makes the difference?

The BREAK will cause the script to leave the current CASE and go to the next CASE if present.
That way the second ->
send mouseup... will be completely ignored.
And this is why it does in fact work, at least for me.
Code: Select all
on commandkeydown tKey
switch tKey
case "1"
send "mouseup" to btn "radio40"
break
send "mouseup" to btn "radio41"
break
end switch
end commandkeydown
If in doubt, please consult the DICTIONARY, which will show you some examples about the usage of a term!

AND that BREAK between the 2 mouseUp signals in the second script will block the second mouseUp.

Frankly I think I prefer your type of phone: certainly less distracting.

You BET!
I own in fact a cellphone and a tablet, but ONLY and EXCLUSIVELY use it to test and run my own LC Android apps!
I don't have the slightest idea why I would need to phone when I'm not at home.

People ring me up when I'm away in the mountains:
"My wife and I have finally made it and she is pregnant; can we put our embryo on the waiting list for your EFL school?"

Each action in a switch statement needs a condition to be matched, a command that executes an action, and a break. The break means the condition matched and the code should exit the switch construct. So you need a case condition for each key press. When the key press matches the case condition the command will execute and the switch will abort.
On Windows, the command key is the Control key. If you use control-1 to test you should see one button respond to mouseUp, even with your currently incorrect syntax. When you provide a case statement for every key then they should all work.

Also, the handler is in the card script because that is where LC sends key press messages. In addition, it allows you to handle all key presses in one place which is good coding practice.
