Reachan!!! First of all, thank you for your valuable review. The basic production principle of this video related to the part you pointed out is as follows. At least, the options of the sample commands quoted in the video explain the function of the option with animated balloon help. However, for some command options, if the viewer can sufficiently guess the context of the example without balloon help, the balloon help animation is omitted. And, I am sorry, but I am only human, so there may be some commands that I missed. Each and every one of these valuable opinions is a stimulus and strength to me. Reachan, thank you very much :)
