Hi all,
I don't know if this is already a faq, but as I have struggled with this issue for quite a long time, I care to share my "discovery":
when I want to set a bookmark with the Command-F2 shortcut, I need to press the Command key first, the 'fn' key second (otherwise the F2 key increase the brightness of the screen instead of passing the value to the application), and F2 last.
If I press the 'fn' key first and the 'Command' key second, the bookmark is not set.
Best regards,
Giulio Cesare
