emacs mouse shift-select from cursor point

Question

can anyone point me in the right direction to globally define the activation of shift select with the left mouse button? I want to be able to select between the cursor point and the selected area... It is possible to drag-select only, and it is possible to shift-select via keyboard only.

This unfortunately doesn't work (in ~/.emacs):

(define-key global-map (kbd "<S-down-mouse-1>") 'shift-selection)

Machine: Win7, Emacs-Version: 25.1.1 (i686-w64-mingw32) of 2016-09-17

Thanks.
