I have been trying set up a script that will select all the text in the open document and change the kerning to optical. or even a script the will change the kerning in the style sheet to optical. Either one would be great
this should get you started
tell application "Adobe InDesign CS6"
activate
set aDoc to active document
tell aDoc
set myText to object reference of paragraph 1 of story 1
set applied font of myText to "Helvetica"
set font style of myText to "Bold"
set point size of myText to 10
set kerning method of myText to "Optical"
end tell
end tell
