Snapping Enable/Disable shortcut while in Create Box tool

While Create Box tool is open I try to draw the box aligned/snapped to the face of another object (say another box), I cannot toggle the Snap mode (using default shortcut key [CTRL] + X1 (mouse back button).

My intention/workflow is like this:
- Create a box to align to
- Create another box I want to align with first box
-- Enable snap mode (face snap)
-- Draw the box start face, snapping with first box
-- Disable the snap mode
-- Drag the end point of box freely without worrying about snapping unintentionally


I can however use the menu-strip/toolbar to toggle the snap option though.

I think this might be a bug of some sort but thought I would post in general just in-case some configuration issue might be in place.

This works, I can now switch between snapping on/off while aready using create box tool.

Thank you
