Animation Editor MMB (middle mouse button) loss of functionality

Hi,

Can someone else confirm that the Alt+MMB combination doesn’t create keyframes on multiple channels when multiple channels are selected in the Animation Editor?

I can zoom-in/out while dragging with the MMB but can’t create keyframes with it. I can only create keyframes on single channels with Alt+LMB but not on multiple channels with Alt+MMB contrary to what is stated here.

I did check that my mouse has its middle button configured as the MMB and not some other fancy feature.

Using build 2022.29530 on Win 10 btw.

Thanks!

Note: just tried on build 2022.33600 with the same result.
