    Abstract: A method and an associated computer program product, computing system, and process for supporting computer infrastructure for prompting an end user with a preferred sequence of commands which performs an activity in a least number of inputs. The method begins by monitoring a computer system for both input received from the end user and state transitions as a result of the computer receiving the end user input. The input received facilitates an activity the end user whishes to execute; the state transitions being the result of executing the activity. Next, defining the input received from the end user in a meaningful way. Then comparing the input received with at least one other command sequences that accomplish the same activity as the end user's input. Finally, prompting the end user with a preferred sequence of commands which performs the activity with the least number of inputs possible.

    Abstract: A pendant mounting structure comprises a main body, a cantilever and two latching elements. The main body includes a first surface and a second surface opposite to the first surface. The cantilever protrudes from the first surface. The latching elements protrude from the second surface. The pendant mounting is separately manufactured and latched to a housing. Thus, when an external force exerted on the cantilever is more than the offset limit of the cantilever, the cantilever could be cracked to protect the housing from being damaged.
