Delete keeps a contact out of this sweep only. Shift+Delete removes the row the same way and stages a lock, so no later sweep takes the contact. The locks are written on Apply with the archive; Esc and Back ask before they discard them. A preview left with only locks applies them without the amber confirm. The footer names ⇧Del lock only when the hint still fits 72 cells, and a contact row now says Enter open, since Enter opens its node page. On the handhelds, Lock rides Shift+F3 behind the Delete chip. Co-Authored-By: Claude Haiku 5.5 <noreply@anthropic.com>
