what is "page_id" in the Modern UI?

Taken from the Modern UI documentation,

!insertmacro MUI_STARTMENU_WRITE_BEGIN page_id
  ...create shortcuts...
!insertmacro MUI_STARTMENU_WRITE_END 

what is page_id exactly and what value do I put there. I just can't seem to figure it out from reading the Modern UI readme.

A unique id for that start menu page so you can include multiple start menu pages. I was just looking at the same thing, hehe 🙂

Just specify the same string for everywhere you use a macro for that specific start menu page. It doesn't go into the installer, so it doesn't matter if it's long or short.

Awesome, thanks.
