The invention provides a method and system for entry and editing of multimedia objects for communication and presentation, associating multimedia objects with received sequences of keystroke or mouse action abbreviations. When an abbreviation is detected, the abbreviation is replaced with the associated multimedia object. Each multimedia object has editable properties, and each set of multimedia objects can be collected into an ensemble, which itself can have editable properties. One such ensemble property is a “theme,” which presents a variant of each multimedia object consistent with the theme.
