Right now when I MMB move it rotates turn-table style, whats the hotkey to free rotate around an object and return to turn-table?
There is a solution to this, but it's a work around.
You can set an empty at the center of your focal target, and parent your camera to it.
To do that select the Camera 1st, then while holding the Shift key select your Empty.
Then on your keyboard Ctrl+P to parent.
To get the turn table effect go into camera view Numpad 0, then select your empty and rotate it about the Z Axis.
Then use middle mouse as your trackball.
You can actually make a hotkey to toggle the option, though figuring out how seems to involve bouncing through the python API documentation and blindly flailing about until something related to what you're reading about actually works.
The solution is: make a new keybind in the
3D View (Global) category with type
wm.context_toggle_enum, set the Context Attribute input to
user_preferences.inputs.view_rotate_method, and set the values to
TURNTABLE. It should look like this:
Though if you use my hotkey you'll want to remove the one for quitting on ctrl-q. IMO that might be a good idea anyway >.>.
Unfortunately, their is currently no keyboard shortcut. (Although someone could right an addon for that)
However you can, if you feel the need to use both rotation modes at once, just set the orbit-style to Trackball in the user preferences and then use Ctrl+Alt+Mouse Scroll to rotate around; turn table-style.
