Abstract

Methods and apparatus implementing a technique for applying suites of operations to selected data through a user interface. In response to a selection of data from a user through a user interface, the user interface creates a specifier object which binds implementations of operations provided by the user interface to the selected data according to the type of the data. In general, the technique includes receiving a selection of data having a type from a user through a user interface of a computer program running on a computer; recognizing the type of the selected data; and creating a specifier object according to the type, where the specifier object specifies an implementation of an operation.
