Why is it that sometimes I can't delete some of the key frames for a garbage matte?

I'd like to be more specific but I've being trying to determine a pattern for the past few minutes and can't! It doesn't seem to happen with key frames I create using the key frame button, only with ones created automatically when you reposition the matte (and it isn't very time even when you do that).

I have two key frames on my current garbage matte (one in the middle of the timeline where I accidently created it rather than at the start) and one added at the start when I moved the matte. Any extra ones I add or the system adds I can delete but those first two just won't budge. Any clues?

You always need at least one keyframe for an attribute, otherwise the program wouldn't know what setting to use. Therefore there always has to be at least one keyframe left. If you expand the tracks fully you'll probably find that the remaining keyframe is the only one on that attribute track.

There seems to be one in the middle (the first one from when I created the matte) and one additional one on the first frame which I created to set the settings from frame 1).

In that situation, where I accidentally create a matte in the middle of the timeline rather than frame one, do I need to copy the settings to frame one and create a key frame or will the program just use the same settings throughout even if the key frame is in the middle?

Can't you just move the middle key frame to the first frame?

Yes you can, thanks. I'm embarrassed to admit that I hadn't realised you could drag key frames. This is going to make things so much easier!

Thanks for the tip.
