Reading those suggestions again, I think I don't understand #3.
Ah, sorry.Basically, the cursor is placed wherever I click on the editor screen. So, if I click in an empty part of the screen, the cursor goes there. that's of no use. Most editors I know will place the cursor at the end of the line of code on the horizontal line I clicked on.
So, when I left-click to place the cursor onto a line of code, if I click on the text, the cursor goes where I expect it to. But if click outside of the text, the cursor is placed exactly where I clicked, even if that place is far away from any code. I expect it to be placed at the end of the line of code just to the left of where I clicked. I'm not sure what value there is in having a cursor off in empty space.
