To set up a custom Fn hotkey in MMBasic, use the following syntax:

OPTION F8 “RUN “+chr$(34)+”myprog” +chr$(34)+chr$(13)+chr$(10)

On my PicoCalc, I configured F6 to launch rgpapp’s [Picocalc Commander (PCC) file manager](https://forum.clockworkpi.com/t/picocalc-commander-pcc/19689) by running the following command:

`option F6 "RUN "+chr$(34)+"b:/pcc" +chr$(34)+chr$(13)+chr$(10)`

If curious:  
chr$(34) = Double Quotes  
chr$(13) = Carriage Return  
chr$(10) = Line Feed
