i can assign the access key or alt+char to any of push button by giving the label as E&xit then x is under lined.
but i want to use the access key to a text item as
my Name <text box for my name>
i want to under line the prompt name N and if i press alt+N then it should go to text item myname.
You can't do that. But you can do by creating a button of 0 width and 0 height and in property
pallete set access key that you want and then in when button pressed trigger write go_item. And
for label you may have to use two or three text item (Label) and just use underline option which is
just near to Bold option.
you may use a push button and assigne your required access key to that and keep the height 1 and width 0
as soon as you presses the desired key combination it will press that push button
then you need to write on when-button-pressed trigger to that push button to go_item('sss') where sss is the destination text item.
