How can I activate the context menu in the Unity Editor via the keyboard?

Does anyone know how to activate the context menu in the Unity Editor using only the keyboard? This would be the same as right-clicking on an object or item in the Editor window, but with a key. Normally I would do this with the "context menu" key on my keyboard, but it seems to do nothing in the Editor.

This would speed up my work, especially when adding a number of new objects. :-D

Thank you for any help anyone can provide!
