Well you can run by holding CTRL, but I'd prefer that CTRL toggled running (or that users could set a default speed with a slider somewhere.)
Yes it does. You just hold a SHIFT key down.
Using the mouse it is too easy to change the eye height as moving up and down also happens when SHIFT is held.*
So SHIFT+RightArrow or SHIFT+LeftArrow is more advisable when "shifting right or left".
* Note that the whole time that the Walk Around tool is active, that the VCB displays the eye height, and is always ready to accept a new value simply by typing and then ENTER. So, at any time with meters as the model units, the user can simply type
1.68 and ENTER on the numpad (or with the left hand on the main keyboard,) and the eye height will be changed. (If inches or architectural units are used typing 66 and ENTER is the same.)
I have been trying to find the setting for default eye height, but cannot find it. On my SU2016 machine no matter what template I use, the Position Camera tool sets the height to 0". Even if I save the model having set eye height to 66", upon reopening the model, and using Position Camera, it's back to 0". Or perhaps the culprit is the Look Around tool ?
