111 "Pop up a deck-of-cards menu and return user's selection.\n\
112 POSITION is a position specification. This is either a mouse button event\n\
113 or a list ((XOFFSET YOFFSET) WINDOW)\n\
114 where XOFFSET and YOFFSET are positions in characters from the top left\n\
115 corner of WINDOW's frame. (WINDOW may be a frame object instead of a window.)\n\
116 This controls the position of the center of the first line\n\
117 in the first pane of the menu, not the top left of the menu as a whole.\n\
119 MENU is a specifier for a menu. For the simplest case, MENU is a keymap.\n\
120 The menu items come from key bindings that have a menu string as well as\n\
121 a definition; actually, the \"definition\" in such a key binding looks like\n\
122 \(STRING . REAL-DEFINITION). To give the menu a title, put a string into\n\
123 the keymap as a top-level element.\n\n\
124 You can also use a list of keymaps as MENU.\n\
125 Then each keymap makes a separate pane.\n\
126 When MENU is a keymap or a list of keymaps, the return value\n\
127 is a list of events.\n\n\
128 Alternatively, you can specify a menu of multiple panes\n\
129 with a list of the form (TITLE PANE1 PANE2...),\n\
130 where each pane is a list of form (TITLE ITEM1 ITEM2...).\n\
131 Each ITEM is normally a cons cell (STRING . VALUE);\n\
132 but a string can appear as an item--that makes a nonselectable line\n\
134 With this form of menu, the return value is VALUE from the chosen item.")
