> I nearly cut an interview short once when I saw someone right click copy right click paste

I like to live in the terminal, but I still sometimes do that. There are multiple clipboards, so using the mouse might sometimes do something different and sometimes I'm just tired and want to use my hands in a different position. And if I selected with the mouse its not much more effort than stopping the selection. You press down left for the selection, move for selection, at the end roll the finger over to the right mouse button without lifting, continue moving so the pointer goes over the rollover and lift the finger again once the pointer is over the copy action. This is the same amount of finger lift than just stopping the selection. Then pressing one or two keys on the keyboard are two finger movements more.
