Copy entire frame

[Spooky Bunyip]

I have a spritesheet I'm working on where I want more or less the same animation, but from multiple angles.
The down angle is 10 frames and I want 8 directions, so I want to start off by copying those 10 frames 8 times so I have a base to work from.

But I can't seem to find a way to copy a group of frames. In fact I can't seem to find how to copy a single frame.

Would anyone know how to do that?

In the timeline you can select what to copy by holding shift (from/to) or ctrl (select multiple without selecting everything in between).
Then pick a frame, click and drag it to where you want it in the timeline but before dropping it hold ctrl.
This will result in the cursor changing now having a + symbol for copying.
Release and done.
