Highlight text, then middle click
Highlight text, then middle click
In many cases I do just highlight and right-click where I want the text pasted. But that workflow doesn't work a large portion of the time and I need a clipboard that isn't being wiped out almost any time I click on something.
Oof, is this the normal Linux behavior? That sounds annoying. In MacOS every app (or even tab) has its own separate highlight that it maintains. So in your example, selecting text in the browser would leave the terminal unaffected, and when you bring the terminal back to the foreground your text is still highlighted.
Muscle memory and 'the way things work' works both ways. You have to jump through hoops to do basic things like focus-follows-mouse/raise on click, multiple desktops, alt-drag to move a window etc (to be honest I'm not sure if you can even do those on a mac)
If your trackpad has multitouch, triple touch should correspond to the middle click. Works for me on Linux by default.
