+This controls the position of the top left of the menu as a whole.
+If POSITION is t, it means to use the current mouse position.
+
+MENU is a specifier for a menu. For the simplest case, MENU is a keymap.
+The menu items come from key bindings that have a menu string as well as
+a definition; actually, the "definition" in such a key binding looks like
+\(STRING . REAL-DEFINITION). To give the menu a title, put a string into
+the keymap as a top-level element.
+
+If REAL-DEFINITION is nil, that puts a nonselectable string in the menu.
+Otherwise, REAL-DEFINITION should be a valid key binding definition.
+
+You can also use a list of keymaps as MENU.
+ Then each keymap makes a separate pane.
+
+When MENU is a keymap or a list of keymaps, the return value is the
+list of events corresponding to the user's choice. Note that
+`x-popup-menu' does not actually execute the command bound to that
+sequence of events.
+
+Alternatively, you can specify a menu of multiple panes
+ with a list of the form (TITLE PANE1 PANE2...),
+where each pane is a list of form (TITLE ITEM1 ITEM2...).
+Each ITEM is normally a cons cell (STRING . VALUE);
+but a string can appear as an item--that makes a nonselectable line
+in the menu.
+With this form of menu, the return value is VALUE from the chosen item.
+
+If POSITION is nil, don't display the menu at all, just precalculate the
+cached information about equivalent key sequences.
+
+If the user gets rid of the menu without making a valid choice, for
+instance by clicking the mouse away from a valid choice or by typing
+keyboard input, then this normally results in a quit and
+`x-popup-menu' does not return. But if POSITION is a mouse button
+event (indicating that the user invoked the menu with the mouse) then
+no quit occurs and `x-popup-menu' returns nil. */)
