> I want terminal editor that does not need me remembering keyboard shortcuts to edit things.
Keyboard shortcuts are essential to increase efficiency and speed. For example, ctrl-c, ctrl-v, ctrl-z, ctrl-s, ctrl-p, ctrl-a etc. People learn these early on if they regularly have to input/edit text to speed up their workflow. Otherwise, they would have to resort to pointing and clicking through menus to accomplish the same thing.
The longer you use an editor, the more of these shortcuts you commit to (muscle) memory, so, even if the commonly used editing operation is easily accessable via the GUI interface, people are going to choose the keyboard shortcut to do the same thing since it's faster.

You could navigate with the mouse or arrow keys in either vim or emacs. The only thing you would have to learn is how to save the file. You may not even have to learn that because both vim and emacs display a dialog box asking you whether or not you want to save the file if you try to exit the editor without saving first.
