I was looking for some way to add a lot of frames in a SpriteFrame without had to do it one by one, and then a realize that Godot already let you do that by multi-select files, but, for some reason, i can't do that. I try select one and push Shift and the down or up arrow and i try to use the mouse, but nothing happens. I even try in 1.1 and Mono, but nothing.
Why this is happening?
Godot version: 3.2.3
SO: Windows 10 (1803) (64-bits)
