This function is not limited to Terminal, it can also be used in the browser. You first select a piece of text (left mouse button dragging/double left mouse button click), and then click the middle mouse button (press the pulley as a button). After completing the copying process, it will be very efficient once you get used to it (if you are not used to the middle mouse button, you can also copy using the shift+insert keys).
There is no such function. Left-click dragging only selects, copying and pasting still require confirmation from the right-click menu.
Select to copy, right click to paste or ctrl+v
