description: if change the carriage style, it saves it as the next option in the cycle.  
if carriage style is unchanged, options were changed and options are saved, it saves the carriage style incorreclty. if options are exited it does not change.

system: win 10, intel x64_86, AMD radeon vega graphics

how to replicate: go to options. change carriage style to [0-1], go to excercise, notice that carriage return style is [q-p] the same is true for [f1-f12] -> [0-1] and [q-p] -> [f1-f12].

so, it's perfectly functional, just not what is expected or intended.
