The scroll wheel behaves differently on Mac and Windows versions. Which are you using?
To use a script to select a specific tab...
Enter layout mode.
Select each tab in the control one at a time and enter an object name in the Inspector Palette (FMP 11) or Object Info (older versions).
IF the object name for the desired tab is "tab one", then your script would use:
Go To Object ["tab one"]
To select that tab.
Ah, thank you, PhilModJunk. I'm using Windows XP
I don't use the scroll wheel often. A quick check with a form view layout of one record wouldn't scroll the window no matter what I tried, but may be I didn't try the right combination. Obviously, with more than one record, I could scroll from record to record, but that wasn't what you asked for.
There are no settings in Filemaker for changing scroll wheel behavior.
Oh, all right. Thanks for all your help again, PhilModJunk! :)
