I created some MenuItemfunctions for navigating, which are currently displayed on the menu toolbar. The C# code:

using UnityEditor;
using UnityEngine;

public class Menu : MonoBehaviour {

static void rotateView(Quaternion rotation) {
    SceneView.lastActiveSceneView.LookAt(SceneView.lastActiveSceneView.pivot, rotation);

    SceneView.lastActiveSceneView.Repaint();
}

[MenuItem("View/Front _1")] // FRONT
static void FrontView() {
    rotateView(Quaternion.Euler(0, 180, 0));
}

[MenuItem("View/Back &1")] // BACK
static void BackView() {
    rotateView(Quaternion.Euler(0, 0, 0));
}

// Few more similar functions

}

I came from Blender, where there are shortcuts opening a context menu on the cursor position like this one, opened after pressing U:

What I want to do is displaying a context menu after pressing P which would display a list of implemented MenuItems. Is something like this possible in Unity?
