1. A computer implemented method for managing objects using predetermined master commands, the computer system comprising the steps of: (a) providing a first object of a first object type; (b) providing a first source application; (c) associating said first source application with a first source operation; (d) associating said first source operation with a first source command; (e) providing a second file of a second object type; (f) providing a second source application; (g) associating said second source application with a second source operation; (h) associating said second source operation with a second source command; (i) associating a master application with said first application and said second application; (j) associating a first master command with said first source operation; (k) associating a second master command with said second source operation; (l) requesting a first source operations list from said first source application; (m) providing said first source operations list from said first source application to said master application; (n) wherein said first source operations list comprises first information relating to said first source operation; (o) requesting a second source operations list from said source application; (p) providing said second source operations list from said second source application to said master application; (q) wherein said second source operations list comprises second information relating to said second source operation; (r) associating a first predetermined command with said master application; (s) associating a second predetermined command with said master application; (t) associating said first predetermined command with said first source operation using said first information from said first source operations list; (u) associating said second predetermined command with said second source operation using said second information from said second source operations list; (v) associating a input device with said master application; (w) using said input device to select said first predetermined command and said first object; (x) executing said first source operation on said first object in said first source application in response to said using said input device to select said first predetermined command and said input device; (y) using said input device to select said second predetermined command and said second object; and (z) executing said second source application on said second object in said second source application in response to said selecting of said second predetermined command with said input device.
