New Keyframe (F6?)

Hello community. I’m having trouble with keyframes and was hoping that someone could help me out. This is my situation…

For a layer on the stage, I’ve placed a movie clip on frame 1. I jump to frame 10 with my mouse and press f6 to make a keyframe. The only problem is that my movie clip is only visible in frame 1 and 10. The clip doesn’t appear in frames 2 - 9. Am I supposed to press something other than f6?

Following those steps doesn’t lead me to the same result. I can see the clip in frames 2-9.
