Some good stuff in there, thanks for sharing. 
Especially like Shift+E (won’t forget that).
It’d be great to find a laptop friendly / trackpad solution to ^this^. Often stuck without a mouse on trains / buses / cars / planes (plus cramped hot-desk swap type spaces). 
So easy with a mouse… But again need to find laptop trackpad workaround. Some laptops offer middle mouse button if LMB / RMB clicked at same time, but not this rig sadly. 
When moving meshes at a distance in large levels at certain angles, the X or Y part of the gizmo can be effectively blocked / obstructed by the Z-axis. That was the reason for asking if there was another way maybe to lock 2 axis to avoid triggering Z with X or Z with Y???
