A computer system edits a first electronic slide deck by reusing content from a second electronic slide deck, the electronic slide decks containing first and second sequences of slides respectively. The computer system identifies at least a second of the slides of the second electronic slide deck as a candidate for insertion in the first electronic slide deck by identifying the second slide as having a target positional relationship with a first slide of the first electronic slide deck. In response to the user accepting a suggestion to insert the second slide into the first slide deck, a version of the second slide is inserted into the first slide deck at a position in the first sequence that is determined automatically by the computer system.
