test_copy.blend Hello, dear developers!
I described the problem at blenderartists.org . Since there was no answer, I decided to report this as a bug here.
It seems impossible to perform a simple operation of copy-pasting keys using Graph Editor.
Please, see file attached.
Take bone "center_top" (selected in the file). I have keys on X Scale and Z Scale curves and on Y Location curve. They look almost the same, but they are different and were created by inserting keys by hand, not by copying from each other. I want to copy, say, X Scale keys to Y Scale curve (in order not to make them by hand). Instead, Blender copies keys not from X Scale curve to Y Scale curve, but from Y Location curve to Y Scale curve, although I did not select or copy from Y Location.
And what is more interesting, if I delete Y Location curve keys, and try to copy from X Scale to Y Scale, there will be no keys pasted at all.
And furthermore, if there are keys at Y Rotation and at Y Location and I try to copy X Scale to Y Scale, it will choose Y Location to copy from...
Is it possible to just copy what has been taken into copy/paste buffer, no matter from what curve and even from what bone?
Thanks in advance,
Regards,
Anna

@JoshuaLeung, think you're most familiar with that area. Is it just some known limitation or actual bug?

When I tested this, I couldn't get anything weird to happen (and especially nothing like what was described here). So, I'd recommend paying close attention to which channels you've got selected (check which ones have their names shown in white in the channels list) when copying AND also when pasting.

In this case, it might help if you could record a short video of yourself performing the steps needed to reproduce the problem so that we can figure out what's going wrong here.

Hello, Joshua. Thanks for your reply.
I recorded a video showing what is happening here: bandicam 2016-09-28 16-34-04-162.avi
It's without sound, so I'll comment.
I take a bone called "center_top". Then I want to copy from Z Rotation of a bone called "crystal" to "center_top" X Rotation. Sure I get selected the bones and the channels, which I do mean. No way - instead of getting the keys I need (about 20 keys), I get some strange 4 keys. Where they came from, I do not know. Oh, I see, they come from "crystal" X Rotation. But you saw that I selected "crystal" Z Rotation, not X Rotation.

Ok, let's try to copy from "crystal" Z Rotation to "crystal" Z Scale. I delete the keys that happen to be at "crystal" Z Scale. Then I paste the keys that I previously copied at "crystal" Z Rotation. And I get some unknown stuff again... 4 strange keys. Where did they come from? Now, they come from "crystal" Z Location? No, I did not even select it.

Really, either my computer, or my Blender copy is funny.
I'll be really grateful if you help me with this, because I really need copy-paste function at keys. I'm not new with animating things, but I cannot win this problem with blender for about half-year... or a year... I am constantly getting some strange stuff when copying and I have to create keys by hand, for I cannot copy them.

@AnnaOKey Sorry for the very late reply. The video recording doesn't show the mouse cursor, so it's impossible for us to see what you're doing.

I've tried copy-pasting both with 2.79 and 2.82 alpha (87b551e836), and it all seems to work fine. These are my steps:

Deselect everything with {key Alt A}.
Drag to select the Scale X keyframes.
Copy the frames with {key Ctrl C}.
Click on the Scale Z channel to make it active.
Position the playhead so that it is at the position of the first keyframe I want to paste.
Press {key Ctrl V} to paste the keys.

If this is still an issue, please provide a clear description on how to reproduce the issue.
