I have a new layer consisting of more than 540 "frames" (not yet technically frames, only the first one is a frame. It is like a default layer in a new project).
How can I select the whole layer so I can transform all of its "frames" into keyframes?
I know I can drag-select but it takes time 'till it reaches the 540th frame.
shift-click frame 2 and while holding down the shift key click frame 540 (to select all the frame), right click, click convert (NOT insert) to keyframes (or convert to blank key frames).
