Select tile

Not entirely sure I understand your question. The frame edit panel is used to edit frames of an animation, so to use it you first need to have an animation. The animations are based on the order of tiles in the canvas (left to right, top to bottom) The selected frame of the animation is displayed in the frame edit panel, and you can switch back and forth between frames using the controls below the frame, "." and "," or Ctrl + scrollwheel.

Hope that helps.

Thank you so much! You solved my problem! For me it was not clear, that the animation must cover the frames I want to edit. The default range for the animation was only Frame 1 - 4.

Now I can start working :)

Thanks again!
