Menu 1st in neo grub

Hi, I did manage some months ago to add some information into the menu 1st option that was using notepad to boot into a Linux OS on a USB stick. I cant remember if it was from the OS that was on the memory stick , or from the ISO file. The menu 1st file was in the NST folder, and the first word was title, but for the life of me i cant remember what came next. Can you help me please.
Regards, Robert.
