[Elecraft] FPLY menu selections

[gehringc at charter.net]

My K2 is working great.  Even after six months I am still exploring and playing with the options.  Last week I started working with the Fast Play option.  I am a little confused with the selections under FPLY.  The first FPLY selection 2-5 is self explanatory, memory keys 2 thru 5 are selected.  However the other available FPLY options are confusing.  45, 458, and 23.  Is there only one available FPLY option?  What do these other FLPY menu items mean?
