Toggling on and off the point creation

When the point creation has been enabled for a road, the button gets checked, as illustrated below:

On the first click, a road point is created under the mouse position, at altitude zero. While the point has not been created, camera movements are disabled and clicking the left mouse button triggers the creation of the road point. Then, the road point creating button goes unchecked and camera movements are enabled again.

To create multiple points and quickly navigate / create point / navigate / ..., press 'space'. Pressing 'space' triggers the last on / off command that was activated. If the last on / off button that was pressed is the road point creation, then pressing 'space' will activate or desactivate it.

Undoing with Ctrl + Z may also be helpful to cancel unwanted point creation, when a camera movement was intended.
