Shift-click and Ctrl-click to multi-select tabs for dragging like in Chrome

It would be nice if:

- Multiple file tabs could be selected at once;

- Ctrl-click would add or remove the clicked tab;

- Shift-click would select a range of tabs;

- Ctrl-Shift-click would add a range to the selection.

Then the set of tabs selected could be dragged out into a new window or between windows, as is already possible for single tabs.

Google Chrome implements this if you want an example. Bizarrely I first had a dream in which it was possible in Chrome, then woke up and tried it and it worked!
