I've been watching tutorials and trying Addons, that led me to install Sensei Format addon, I didn't like how it changes many of the shortcuts that I got used to, yet one feature grabbed my attention, when clicking to set the 3D cursor in 3D view, if I click on an object, the 3D cursor location will snap to the object's origin. While reviewing Sensei Format, I found out that it's basically a personalization of features that already exist in Blender and in other Addons, for instance I managed to call the create object menu in 3D view by double right click instead of Shift + A. Is there an Addon, or a way, to activate the 3D cursor snap to object origin in 3D view?
You don't need an addon to do that, you can achieve it with Blender's builtin key map editor.
If the default Shift + S > Cursor to Selected is not enough for you, then you can set up any desired key combination to call that operator for you in the key map editor. The operator you are looking for is
With this you can go to Blender user preferences with Ctrl + Alt + U > Input Tab > 3D view > 3D View global and add a new entry there with the Add new button at the bottom of the list
In the operator field to the left enter the
view3d.snap_cursor_to_selected now assign any mouse action or key press as desired.
Depending on which mouse button you use for selecting I found out that using the same mouse button plus some modifier key can work very well.
For example I use Left Mouse button for selection, since in object mode the F is not bound to any action by default, I assigned Mouse Select > Press + F as modifier key to
view3d.snap_cursor_to_selected so when I am selection objects all I have to do is press F key and click on an object and the cursor will snap to all selected.
Edit Check out the example image
In object-mode you could go to Object > Snap, right click on Cursor to Selected and choose Add Shortcut to turn this into an immediate action.
