Can't select multiple notifies with mouse left click & drag in the Persona

[JoCo]

Hi all,

My team has recently migrated to 5.5 and just realized that, in the Persona editor for animation sequences and montages, it was now impossible to hold the left mouse button somewhere in the timeline to select multiple notifies (and notify states).
It’s like, the click & drag behavior to make a simple selection rectangle is now gone.

5.4 and prior

Is that just hidden behind some keyboard shortcut now?
(like.. Shift + LMB or something?)

Any help would be greatly appreciated. This makes copy / pasting bulks of notifies from one anim to another really tedious.

Cheers,
Jonathan

Found it!
It’s Alt + LMB click and drag

(Ctrl + LMB does this weird grey time-range selection.. does anybody know what it is?)
