While using the JKL feature in Final Cut Pro 1.2.1 or 1.2.5, and holding down the K and L keys on the keyboard, I tried to mark an IN point with the I key. Nothing happens.
Solution
With Final Cut Pro 1.2.1 and 1.2.5, you can navigate a clip or sequence at less than 1x speed by holding down the K key, and holding down the J key for reverse or the L key for forward. While using this function, you may be unable to mark an IN or OUT point using the I and O keys on the keyboard. Instead, use the / and * keys on the numeric keypad to set an IN or OUT point.
