Advanced Ui input method

Hi, I am learning advanced ui input and output methods, part of this I tried 3 methods in notepad . When I tried with windows method its not converting in to lowercase letters and when I used simulate method its not clearing the previous statement(regarding empty field) and i cant see keyboard shortcut(enter).Please help on this.

Thanks.

Why are you using click activity?
You are testing the the methods, and i think they are for type-into using all 3 options.
