That's because Linux isn't using Tk 8.5 yet.  Debian defaults to Tk 8.5
in experimental since March.  Most Linux is Tk 8.4.

On Windows, our installer is using 8.5.  Here's a screenshot from my 
eeePC, 1024 x 600:

Tal, you've got some catching up to do, yourself.  Tile went into Tk in
8.5, two years ago.  Linux is behind, we don't control that, but our
Windows installer and tkinter is cutting edge!  Thanks, Martin!  I don't
know what version is running on the Mac:

I've got an ancient Python 2.5.1 running in Gnome/gNewSense using Tk
8.4.  I think you guys are  exaggerating.  It's not /all/ that ugly, not by a
long shot.  It's just not native look and feel (yet).

On Linux and Windows, <alt> f  will drop the file menu.

Looks much better in 8.5 and the shortcuts work.

Pull down the format menu.  The dedent hotkey is Ctrl+[

This possibly could be changed to Shift+Tab by the user, but there may
be conflicts with completion.
