Load function list

in scritp editer, i use + to load function list, why the list can not popup?

For me, I have found that it only pops up for the system library.

The function list functions more as an autocomplete for Ignition functions than it does as a quick reference. It will also only show you information on Ignition specific functions which are the functions that start with “system.”. If you type in system. into the script editor and then press ctrl + space then the function list should pop up and show you the functions that are available to you.
