ALT-Y not working

A function I use a lot but is not working 100%. Problem can be seen by downloading this clip

Funny, because I actually had an issue with alt-y not working at all... yesterday.

I'd been using to click an empty place (or a clip to delete) in the TL and then cmd + return to have all the next clips come "sonner in the TL" filling the blank space but it doesn't work anymore by default, so I wanted to replace this and found out that function...

However, alt-y doesn't do anything on my mac, while y alone indeed selects every clip next to the selection...
I have to check again...

Hi SAM,

Here no problem if the Destination Control Enable + Auto Select button ON is activated on a track.
Y => the right of the playhead => OK

ALT + Y on all tracks Auto Select(ed) button ON and the right of the playhead

You can verify ?

Hey JC

I checked and found out that "alt + y" gave weird and random results ...
So I erased the shortcut from my pref and just kept "y" and "cmd + y", corresponding to clips after and clips before on the TL, given that I'm not interested in the "all tracks" action.
Solved for me, thank you.
