I did think of it too but to me it's a poor work around to this problem.
that's why i was thinking of using url block of some sort as a better fix.
I mean when you have a form on a web page (when you press enter in google as
an example it activates the click event).
So here is th question if you have a button and when you press enter you
direct the event to the button and let it do the rest then it'll be a click
event handling the rest of the code.
so to me it'd be some like....
keyrpess do |key|
when :enter
buttonfind.click <- this being a button on screen called find.
when "\n"
buttonfind.click
end
end
_OR_ would this still be a problem?
Changed the keypress to be outside the stack block (it still works on my OS).
could I please get feed back on those using Mac's and Windows please?
on my OS tab moves to the next edit line and shift+tab move back could this
action be confirmed too?
