You're talking about "attribute promotion". An attribute in the symbol may be "promoted" to an attribute attached to a specific instance of the the symbol in the schematic. That's how attributes become editable.

You can manually promote an attribute by right-clicking on it in the attributes menu. Or you may simply attach an attribute to a symbol with a name identical to an unpromoted attribute.

There are arcane rules for automatically deciding which attributes are to be promoted. I usually turn as much of that off as possible by the use of a line like:

(always-promote-attributes '("refdes"))

This makes wholesale changes of attributes by editing symbols more predictable and useful.
