I don't think key repeat time has anything to do with it - that is to do with how long you have to hold a key before it automatically repeats. Separate keystrokes are (or should be) always registered.
What happens when you press Ctrl+C is that your selection is copied to the Windows Clipboard. If the Office Clipboard is running (if you have at least one Office application running) then the selection is also copied to that.
If you press Ctrl+C again, another copy operation is performed exactly as before but there are a couple of things to note:
[ul][li]If what is copied is exactly the same as what is already on the Windows clipboard it may or may not be overwritten - it's impossible to tell.[/li]
[li]If what is copied is exactly the same as what is already in the latest slot in the Office clipboard it may or may not be overwritten - again, it is impossible to tell - but a new entry will not be added.[/li]
[li]If nothing is selected when a copy is performed, no data is copied either to the Windows Clipboard or to the Office clipboard.[/li]
[li]By default, two successive copy operations (with nothing but an intervening paste) within the same Office application, whether or not any data are actually copied, will trigger the display of the Office Clipboard in that application.[/li][/ul]
So, pressing Ctrl+C twice in, say, Word will copy the selection twice - see above for the impact of the second copy - and display the Office clipboard. If the selection was just an insertion point, nothing is actually copied; if it contains data, that data will appear in the latest slot.
It may or may not help you, but I wrote an article on this subject for
VBA Express (and I think you can view it without signing up). The formatting on some of it isn't quite right and I am thinking of expanding it a little but it covers most of what happens.
Enjoy,
Tony
