Thank you again to be so prompt to answer!
I think I must be a little stupid or blind
because I check on the main toolbar (top window) in the item format
where I find the next items Layout, subtopics, shape, numbering, checkbox, arrange
and try to find in those items section a list with the kerning, ligature, baseline
but didn't find anything such like that.
I try to to find in the help section on the web words baseline, ligature
and just find kerning.
I think indeed there must be a difference between Mac and Pc version.
Maybe could you send me to my email adress (or me to you if possible) a screen copy of your (my) Novamind to be sure there is no misunderstanding from me, and so that there is is a different ergonomy for Pc and Mac?
Anyway thank you for the time you took to answer me.
