You can manipulate Grease Pencil frames on the Time Slider much the same way you manipulate keys.
- Select the frame (or Shift-select multiple frames) you want in the Time Slider, then right-click and select Cut, Copy, or Paste.
Note:
- Grease Pencil frames cannot be cut, copied, and pasted between different cameras.
- If the selected frame(s) display both a Grease Pencil sketch and a keyframe on the timeline, this operation cuts, copies, and pastes both.
- If you cut the last Grease Pencil frame in a sequence, a greasePencilSequence node remains in the scene until you delete it by right-clicking the Time Slider and selecting Grease Pencil > Delete Frames > greasePencilSequence.
