I answer myself: I found the solution. It's funny, that's the rewarding 
thing about scripting, you have a problem, you try and retry, and when you 
finally find the solution you really feel fine!

So here it goes:
You have two identical fields (F1 and F2), both are ordinary scrolling 
fields with dontwrap set to false and listbehavior set to false.

- In field F1 you display the phrases. Copy the text of fld F1 to fld F2.
- set the layer of the copied field lower than the layer of field F1 (that 
is, you put fld F2 under fld F1)
- set the textcolor of char 1 to -1 of fld F2 to white - which is the colour 
of the background (in this way the text is invisible)
- move fld F2 a little to the left (0,5 cm or so)
- group the two fields. In the group script put:
            on scrollbardrag
               set the scroll of fld F2 to the scroll of fld F1
            end scrollbardrag

- in the script of fld F1 you put:
  	put word 2 of the clickLine into snr
    	set textcolor of char 1 to -1 of fld F2 to white (deletes the previous 
bullet)
   	put "ﾕ" into char 1 of line snr of fld F2 (this is the bullet 
equivalent, it is not displayed correctly in this email)
   	set textcolor of char 1 of line snr of fld F2 to 255,102,102

I'll upload a stack to show this within a few hours.
