[This is preliminary documentation and subject to change.]
Copy, delete, and paste are based on the standard verbs. The snap-in controls the standard verbs by setting the console verbs when it gets an MMCN_SELECT notification.
If one item in a group of selected items can be copied or deleted, then the copy and delete verbs will be enabled.
Paste is disabled for multiselection.
Copy
Nothing is required by the snap-in to implement copy.
Delete
The snap-in has to handle the MMCN_DELETE and MMCN_CUTORMOVE notifications.
Paste
The snap-in has to handle the MMCN_QUERY_PASTE and MMCN_PASTE notifications.
