If you hit the enter key twice after you are done typing and want to paste in a link the cursor will drop down twice and then you can paste in what you wanted.
I have no idea what you are trying to describe.
If you want to insert a link, say after putting in two periods and a space, like .. HERE .. then one hand went to the mouse, you right clicked it, the menu came up and the paste occurred where you wanted it to, irrespective of where the actual mouse then sat.
The mouse has nothing to do with the cursor after you hit the return key twice.
As for sarcasm you keep complaining about something you should be able to figure out on your own.
