Does the Copy command under virtuoso place db objects into a "paste" buffer that is still maintained after the copy command is terminated which could be accessed with a SKILL command some amount of time later ? Is the buffer erased and filled with a new object once the copy command is started again ? Is there a history associated with copy that I can see ?
Ted's correct - it doesn't remember the shapes with Copy.
However, the Yank command does store the figures in a buffer, and then the Paste command recalls that buffer. However, there is no SKILL interface to access the figures in the buffer.
