Aquamacs Emacs 1.8 RC1 / 1.7

Aquamacs is a Mac-like distribution of the powerful Emacs text editor. By "mac-like", we mean more than just the fact that this version of Emacs runs as a standard OS X application.
Aquamacs features extensive customization that enables it to conform better with Apples standard Human Interface Guidelines (HIG) than standard versions of the editor do.
Emacs is a text editor of legendary power and configurability, but it also has an enormously complex interface that, while consistent across platforms, is usually at odds with the specific interface conventions of the particular platform on which it is being used.
The same applies to the OS X version of GNU Emacs, called Carbon Emacs.
Aquamacs is different: it will provide you a more Mac-like user experience and the comfort youve come to expect from other excellent Mac apps. Aquamacs comes completely configured and ready to go.
It builds on GNU Emacs 22, however, so youll be able to use all your favorite extensions (and even the good-old Emacs key bindings, if you like!).

System requirements:
- PPC (G3, G4, G5) or Intel Mac.

Enhancements
- Tabs are now directly accessible using keys A-M-1,2,3...9,0 (normally: Command-Option-1,2,3...9,0). The number of each tabs is marked. For configuration, see the new customization variable `tabbar-show-key-bindings and the function `tabbar-define-access-keys. For instance, use (tabbar-define-access-keys (alt)) in your Preferences.el file to use Command-1,2,3.. bindings.
- Aquamacs now asks for confirmation when printing is requested via A-p. This helps avoid long waits for rendering with large buffers when A-p is pressed by mistake.
- On systems with faulty LaTeX installations, Aquamacs will now do a better job at choosing the right TeXLive (or legacy teTeX) binaries.
- When scrolling back and forth page-wise, the point will now end up in its previous position.
- Command-, can now be re-bound via the normal Aquamacs key maps (`osx-key-mode-map) . (Note that even if rebound, the application menu will still show the A-q and A-, key bindings for Quit and Preferences, respectively). A-h remains unmappable for now. Reported by Chris Bernard.
- The mark is now deactivated when point is restored while switching tabs (in transient-mark-mode, which is on by default).
- Command-C (clipboard-kill-ring-save) will take care not to create duplicate entries in the kill ring. Reported by Konrad Podczeck.
- Fixed a rare failure of dired to view directories. Reported by Uwe Pieczynski.
- Fixed an error when deleting the whole buffer contents while smart-spacing-mode was on. Patch by Jon Shea.
- Fixed a potential security hole in smtpmail. Code by Simon Josefsson.
- `LaTex-mode-hook can now be customized and saved through the customization interface. Reported by Bruno Cadonna.
- ESS (R-mode) will now retain an active mark (and region) after evaluating code, e.g. with C-c C-r.
- In the keyboard emulation modes that allow the mac-native use of Option on various keyboard layouts, while retaining Option as Meta key for Emacs, ESC key sequences always act as Meta sequences. For instance, with the German layout, ESC-l acts as `downcase-word (the original M-l binding), while Option-l inserts the @ sign.
- Adopting fonts as default fonts for frames: keep frames inside screen. Reported by Stefan Vollmar.
