A plus-button to run the script might perform faster than the script trigger.
Sorry, wasn't clear. That's what I meant when I said I tried with a script (using a button) and "also" a script trigger running the same script. The setField step above is what runs off the button. Client said it seems a little slow and because he's a friend I can say that he is normally a little impatient about most things.
I would have though the SetField option would be the simplest approach for speedy data entry.
Have you asked your friend if it's actually slower than physically writing it onto a piece of paper and tallying it up at the end? Perhaps the data entry process isn't much faster, but the overall result may be. It's all about perception.
We are talking touch-screens here, and their responsiveness is set to make sure every accidental brushing of the surface isn't registered as intentional input. This avoids touchscreen devices becoming too touchy to use. I think the built-in hardware lags just have to be accepted.
I like Marc's comment about perceptions, and all speed is relative. FM Go beats a pad of paper and a really fast pencil.
Very much agree with you both. Just have to convince him. I'll stick with the direct script approach for now. Thanks
