The context-sensitive button mechanic allows one button to serve a variety of functions, such as talking, opening doors, and pushing, pulling, and throwing objects.[e] The on-screen display shows what action, if any, the button will trigger, determined by the situation. For example, if Link is holding a rock, the context-sensitive button will cause Link to throw the rock if he is moving or targeting an object or enemy, or place the rock on the ground if he is standing still.[f]
Where can players see what action will be performed in different scenarios?

The Pro Electron standard, the European Electronic Component Manufacturers Association part numbering scheme, begins with two letters: the first gives the semiconductor type (A for germanium, B for silicon, and C for materials like GaAs); the second letter denotes the intended use (A for diode, C for general-purpose transistor, etc.). A 3-digit sequence number (or one letter then 2 digits, for industrial types) follows. With early devices this indicated the case type. Suffixes may be used, with a letter (e.g. "C" often means high hFE, such as in: BC549C) or other codes may follow to show gain (e.g. BC327-25) or voltage rating (e.g. BUK854-800A). The more common prefixes are:
