Greetings!
I haven't found an option to use the on-screen keyboard to search within the help pages in GrandMA3 onPC so far.
If this is indeed not possible and not just caused by me being as blind as a bat, I'd love to see this added to the software. Especially when I'm travelling with a convertible to program a bit on the fly,
I often don't connect the keyboard and have to rely on WIndows' integrated on-screen keyboard functionality to search within the help pages.
