+        The native control provides a great variety in the events it sends in
+        the different selection scenarios (undoubtedly for greater amusement of
+        the programmers using it). For the reference, here are the cases when
+        the final selection is accepted (things are quite interesting when it
+        is cancelled too):
+
+        A. Selecting with just the arrows without opening the dropdown:
+            1. CBN_SELENDOK
+            2. CBN_SELCHANGE
+
+        B. Opening dropdown with F4 and selecting with arrows:
+            1. CBN_DROPDOWN
+            2. many CBN_SELCHANGE while changing selection in the list
+            3. CBN_SELENDOK
+            4. CBN_CLOSEUP
+
+        C. Selecting with the mouse:
+            1. CBN_DROPDOWN
+            -- no intermediate CBN_SELCHANGEs --
+            2. CBN_SELENDOK
+            3. CBN_CLOSEUP
+            4. CBN_SELCHANGE

+        such originality.
