For an artificial or surrogate key that identifies an instance of a symbol, something like:

COPY
~~~~
1. Copy objects to buffer
2. Assign a new identifier to symbols in the buffer

CUT
~~~
1. Copy objects to buffer
2. Remove objects from schematic

PASTE
~~~~~
1. Copy objects to schematic
2. Assign a new identifier to symbols in the buffer

It would also be nice to have some surrogate key, that could be either artificial or natural to identify a part. For example, if there is more than one symbol to represent a 74HCT00, a refdes renumbering program could identify that all the instances belong to the same part, and assign slots properly. A natural key could be a company part number, but many don’t create company part numbers, so an artificial key may be better in this case.
