A method by which a multimedia presentation editor for use on a (typically handheld) communication or computing terminal (10) interfaces with a user so as to allow the user to create or edit a presentation (20), including: a step (51) in which objects to be displayed successively when a slide (21) is displayed in play mode, are instead assembled by the editor one under another in a column (25a), and objects (22) to be displayed continuously are also assembled in a (one-object-long) column (25b); and a step (52) in which the editor displays each column (25a-b) side-by-side, corresponding to the side-by-side arrangement of respective objects in the different columns (25a-b) when the slide (21) is displayed in play mode, thus allowing some parts of the slide (21) to be fixed, and some parts (23a-c) to change—the parts having columns with more than one object. Corresponding equipment is also provided.
