Abstract: Methods for allowing a user to customize an interface for a computer program are provided The methods allow a user of the computer program flexibility in organizing commands into a menu structure The methods also allow a user of a computer program to assign a keystroke sequence to a command. The user can then invoke the command by entering the keystroke sequence. A command assigned to a keystroke sequence does not need to be associated with a menu. The methods allow the user of a computer program to predefine parameters for commands. The predefinition allows the user to invoke a command without reentering the parameters. In a preferred embodiments, the methods use a command array that contains an entry for each command. The methods use an array associated with each menu. The arrays contain unique identifiers of the commands that are associated with the menu. These unique identifiers are used to reference entries into the command array.
