The arrow keys can be used to change the active card of the stack.
It's not an issue in development environment, I just don't press them

But the behavior continues in the windows standalone app, too.
Now, that's a deal-breaker.
I recall that I saw somewhere in preferences such thing but now I couldn't find it.
How can I disable arrow keys changing cards?
And a follow-up question {actually, this is how I found out the above issue.}
I have a group full of check-boxes which is created on-the-fly.
In other apps {standard Windows or OS X apps},
user can wander around the check-boxes with arrow keys
and highlight or unhighlight the selected check-box with space key.
It's much faster, on occasion, than point-and-click with trackpad.
How can I get same functionality with LiveCode?
Thanks for any help...
Best,
