I have never heard of a setting like for that. I think it all depends on the person using the keyboard.

Small code is done with many sub routines. Say you are using an ADC. If you need to read the ADC many times, have a GOSUB or GOTO a LABEL with everything in that routine instead of rewriting it several times. If that routine has five lines to read the ADC and write it to EEPROM or some place else, then the one GUSUB here and there will end up saving some lines of code. In other words, do not repeat yourself.
