Hello, I’m about to order the F77 keyboard and have a question regarding the right-side block options.

I’d like to use the right-side block in layout no.4 among 5 options, but the selection for the right-side block only seems to allow for option no.1 or no.2 as below.

1. 0-9 and cursor keys

2. Print/ScrLock/Pause/Ins/del + cursor keys.

If I want to use it in layout no.4, would I need any additional extra keys besides the Regular Printed US ANSI Layout keycap set (104 keys)? And I’m also wondering which option I should choose between 1 and 2 if I want to use no.4. 

Thanks!
