If you've used the type library editor in Delphi or C++Builder you've noticed that Cut, Copy and Paste don't work (CTRL + X, CTRL + C, CTRL + V). Well actually it's just Paste (CTRL + V) that doesn't work. To make a long story short the reason for this problem is due to the architecture of the IDE making it impractical to get this to function. The good news is there is actually a shortcut for Paste. So instead of CTRL + V, use Shift + Insert.
