how to set the textStyle of word 1 of the selection?

[Andre.Bisseret]

Peter,

Thank you a lot for your attention to my problem.  I am impressed by  
the way you think about a problem.
Very nice solutions really; works well :-))

Meanwhile, I am trying to edit the selection made by the user, using a  
repeat loop to delete the possible spaces (and/or tab) before the  
selection, for several spaces might be selected before a word.

In fact, my field does not include text. It is populated by the day  
numbers of the twelve months (one line for each month). Generally two  
numbers are separated by one space (weeks are separated by tab).

But before the first of a month there can be several spaces (when the  
month don't begin on the first day of a week.). Not likely the user'  
selection would included much spaces, but 2 or 3 could be possible!

Thank you again Peter

Best regards

André
