It'd be easier to understand using a self-contained example that I'm attaching below.
Here's the steps to show you what I mean:
1. Set focus in column Account and press F2. A dialogue-box box simulating a picklist appear, press Yes (this represent user selecting an account code).
2. Now a validation is done and it's determined this particular account code requires getting additional info. Press Yes at the More-Info dialogue box that appear
3. At this point, the focus is back at column Account. I really wanted it to be in the next column if user did key in additional info at step 2 but I don't know how to programmatically do so.
4. Since now user is at column Account, they'd have no choice but press the right arrow key to go to the next column but this would cause the More-Info dialogue box to pops-up again which is really annoying.
Anyone has any idea how to smooth all of these out?
