Modify: Read vs. Write

When an alert says that an application wants to modify a registry entry, does it always mean a write operation? Does Comodo differentiate between a read and write operation?

The online manual says about Protected Registry Keys:

Comodo Internet Security automatically protects system critical registry keys against modification.
That means that D+ will only alert when an application is trying to write.

D+ does not alert when programs try to read protected areas in the registry.
