A mechanism is disclosed for identifying non-standard user interface controls in a target application. The mechanism includes an accelerator, an agent, and a dialog. The agent is configured to be installed into the target application and to interface with the accelerator. The dialog is configured to select non-standard controls in the target application where each non-standard control includes a set of properties. The agent is configured to provide the properties of the selected non-standard controls to the accelerator. The accelerator is configured to determine a set of common properties for the selected non-standard controls and to automatically generate an identification rule for the determined set of common properties.
