Hotkey to Frame all Objects into viewport? Is it possible to set hotkey F to View/Frame All objects into all viewports, and if any objects are selected will frame that object within all view ports as well with key F.
I would be very grateful for any tips.
To frame all objects in one viewport do: Home or Ctrl + Home Both with the origin as the camera focal point
Or Shift + c
This will also bring the 3D cursor back to the origin.
Numpad . will frame the currently selected object or objects.
Numpad / will frame the currently selected object or objects and hide everything else, until you press it again.
You can change them here (to F):

This however will affect only the (single) viewport under the mouse cursor.
I imagine affecting multiple viewport at once will require a script, but i'm not sure.
EDIT:
If you want to experiment with a different hotkey layout you can always click Add Key-config Preset (the little &quot;+&quot; icon), to make a new preset and try some things without messing up you current key setup.
