[chirp_devel] behavior of "Smart Tone Modes" and "Show Instructions"

Hello,

I am trying to create ja.po (Japanese tranlation) for CHIRP. I want to make a translation to "Smart Tone Modes" and "Show Instructions". It is easy to simply "スマートトーンモード" and "手順を表示" but they don't describe what is there functions.

What does they works? Can anyone tell me how to check easyly these functions?
