Keeping the skateboard until the end of the level? The method can be seen in any TAS. It involves 6 precise button press changes. They can be broken down into two 1-frame, two 2-frame, one 5-frame and one 8-frame tricks (give or take a frame since not all combinations have been investigated). Since you anyways have to lose the skateboard so early in 7-3 (to collect the key), the overall time gain is only about one second.
