This feature is in the tab menu of some other browsers. Not a particularly useful feature from my perspective and I don’t miss it, but I got to wondering. Just because I like to know how everything works.
Is there a keyboard shortcut for it or something like that?
Not sure if you can get to it thru a keyboard shortcut, but if you multi-select tabs (using Shift or Ctrl) and right-click, then Reload, it will operate on all the selected tabs.
