I am using Infragistics NetAdvantage 7.1 and have a question about the UltraWinGrid control.

I have a UltraWinGrid of 50 columns.  On a particular row, i use the Tab key to move to the next cells.
As soon as it reaches the rightmost of the screen, it will scroll to the left by one column.

What i want to do is that whenever horizontal scrolling (trigger by Tab or Enter keys) is required, it
scrolls 5 columns instead of just 1 so that users do not have to keep focusing on the rightmost columns
all the times.

I have looked at the BeforeColRegionScroll() event, but it does not distinguish between a scroll that
results from Tab key versus a mouse click in the empty area of a scroll bar.  

Any idea/suggestion will be greatly appreciated. Thanx.
