Some ways

First : not recomended . USER.name = (((every thing you want))) and if it throws an error ,it says its type by that error details.

Second : select the word((( USER.na》|《me))) and press f12 to see its Ref or type directly.

This 》|《 is sample of your mouse cursor .I mean select the word ((name)) or ((USER)) where you are using it
