# Explain, do, drop or undo any passage

_Release #087, October 21, 2026. Viktor app_

Select text in a Viktor reply and pick Explain, Do it, Drop or Undo. Nothing sends until you hit send.

- **Four one-click presets.** They sit next to Comment in the selection toolbar whenever you highlight part of a reply.
- **Honest undo.** Undo reverses what the passage describes, and says plainly when something can't be reversed.
- **You stay in charge.** Each pick becomes a chip in your message, and nothing goes out until you send it.
