Several mouse clicks with the Ctrl and SHIFT modifiers bring up menus.
This menu is for selecting a buffer.
The MSB (“mouse select buffer”) global minor mode makes this menu smarter and more customizable. See Buffer Menus.
This menu contains entries for examining faces and other text properties, and well as for setting them (the latter is mainly useful when editing enriched text; see Enriched Text).
This menu is mode-specific. For most modes if Menu-bar mode is on, this menu has the same items as all the mode-specific menu-bar menus put together. Some modes may specify a different menu for this button. If Menu Bar mode is off, this menu contains all the items which would be present in the menu bar—not just the mode-specific ones—so that you can access them without having to display the menu bar.
This menu is for changing the default face within the window’s buffer. See Text Scale.
Some graphical applications use mouse-3 for a mode-specific
menu. If you prefer mouse-3 in Emacs to bring up such a menu
instead of running the
mouse-save-then-kill command, rebind
mouse-3 by adding the following line to your init file
(see Init Rebinding):
(global-set-key [mouse-3] 'mouse-popup-menubar-stuff)
