Aquamacs is an Emacs text editor for Mac OS X. It is based on GNU Emacs from the GNU project, currently tracking the version 23 branch, although its user interface (UI) is designed to conform with Mac OS X UI standards.
Among the changes are that Aquamacs, by default, shows tabs to organize different file buffers in windows. A range of keybindings (keyboard shortcuts) that are standard on Mac OS X, such as Command-W to close a window, or Command-S to save the file, are available. A standard printing dialog and functions to efficiently use the Option key on Mac keyboards as Emacs Meta key have been added. The styles of windows can be automatically changed to suit the major mode used in the buffer shown. Visually, Aquamacs has been adapted in its icons and fonts to look similar to other Mac applications.
Aquamacs is a distribution that includes a number of extensions to GNU Emacs to provide an integrated development environment and to support, among many formalisms, LaTeX editing. These packages are installed without the requirement of further configuration by the end user.
