In this paper, we propose some methods to transform fine-grained editing operation history into coarse-grained one. Fine-grained history is suitable for investigating the detail of editing operations or source code changes, however, not for grasping the outline of editing history. We describe filters of editing operation history, fusion of editing operations, and criteria to transform into coarse-grained history. These are expected as useful devices to reduce the number of frames in replaying editing operation history.
