Why can't I used shift/ctrl for selecting multiple tabs/windows?

I believe the current functions for the shit/ctrl + click are rather ridiculous and can easily be implemented with a button or rather just simply removed as one can simply do them with the right click button(I am talkin about google chrome's 'open link in new tab/window').

What I am suggesting is, allow the user to press shift/ctrl and click to select multiple tab/windows and preform a given function, like delete or move.
