Thanks Kevin, this works as well as mouseCharChunk() suggested by Phil Davis.

This fails (I'm using MC 2.2.5 on a Mac) with an error message saying
"bad text attributes, can't get object attributes" which implies that
the function doesn't work with a text chunk! I tried this with:
put the formattedHeight of line 1 to 31 of field doctext1
>Note that selecting the text by script will also scroll the field. (If you

I tried "select line theLine of field theField" and it selected it
ok but didn't cause any scrolling or realignment?!
