This plugin is a basic modeling software that runs in runtime.
Navigation are similar to the UE4Editor/Maya.
Focusing on a point is achieved by pressing on the “.” key on the numpad instead of F ( Like in blender(3DModelingSoftware))
Moving/Rotating/Scale of mesh elements is done using the G/R/S keys and axis constraints for world and local coordinates is done by pressing on X/Y/Z/Shift+X/Shift+Y/Shift+Z (Again, just like in blender).
Editing mode options menu can be opened by pressing Ctrl+Tab ( Like in blender )
More:
Shift+G = ( Selection Options ) ( Like in Blender ) <- In Face edit mode
U = UV Options <- In Face edit mode
Watch the video to get the idea of how it works.
