My keydown event is done like this to register 0-9 button and the delete key from keyboard.

Hi tan,

then you need to add more code to handle other keys as well!

Can you try to show how to handle that + as Add case ? I know that ASCII for + is 43 but how to make the case behave like this ? Because it seems like I need to do it in new key down case.

Thank you for your help. I will proceed with key navigation with F1, F2 ... for each of the case.

Hi tan,

using the F keys is not very intuitive...

You already know how to catch keypress events. You already know how to handle certain conditions like the Delete key. All you need is to handle other conditions like + or *...

As said before: a proper VI design would help you much. What about an event driven state machine?
