1. An interface apparatus for a transceiver of a radio telephone for speed-dialing telephone numbers to effectuate a telephonic communication link with a remote location defined by specific ones of the telephone numbers, the interface apparatus comprising:

  • a main directory having a plurality of main directory locations, each one of the plurality of main directory locations containing a mnemonic and a corresponding telephone number;

    a plurality of subdirectories, each one of said plurality of subdirectories containing a subset of the plurality of main directory locations assigned by a user to include any of said plurality of main directory locations, said subset of the plurality of main directory locations being ordered for access by a user in a user assigned order and wherein each one of said plurality of main directory locations can be assigned to more than one of said plurality of subdirectories;

    a processor operatively coupled to said main directory, said subdirectories, and the transceiver to;

    (a) generate a sequential-access directory pointer for sequentially accessing the main directory locations of the main directory; and

    (b) generate an interrupt-access directory pointer for non-sequentially accessing any of the main directory locations which form the subset of the main directory locations;

    a sequential-access actuation switch actuatable to cause sequential accessing by the sequential-access directory pointer of the main directory locations; and

    an interrupt-access actuation switch actuatable to cause non-sequential accessing by the interrupt-access directory pointer of the main directory locations; and

    wherein said processor transmits the telephone number accessed by either of said sequential-access actuation switch or said interrupt-access actuation switch to effectuate thereby the telephonic communication link with the remote location.
