Already in 2012 in Acrobat XI a new feature was introduced which allows to store information from Output Preview (color value of separations or result of object inspector) as an annotation in the PDF page. To get this the user had to perform a Shift+Click on the page while the Output Preview window was open.
The use of the Shift key as hotkey was unfortunate since the shift key is also used for performing multiple selections with the Acrobat tool Edit Object or the PitStop Inspector. This was no longer possible while the Output Preview was open. Instead of selecting multiple objects Acrobat created unwanted annotations.
