What is a way to enable quick access to a favorite frequency or channel on your transceiver?

Modern transceivers feature memory channels that allow operators to save specific frequencies, repeater offsets, tone settings, and other parameters for quick recall. Storing a favorite frequency in a memory channel eliminates the need to manually dial it in every time you want to use it. The other options serve entirely different purposes. A 'frequency offset' is the difference between transmit and receive frequencies used for repeater operation. 'VOX' stands for voice-operated exchange, which allows for hands-free transmitting. Finally, 'scan mode' automates searching for active signals rather than immediately recalling a known favorite channel.
