Purpose: Document (particularly core distribution) [Tcl] and [Tk] differences
between supported platforms.

   * Features unique to [X] Windows versions of Tk
   1. -display support
   1. The [send] command (while [Mac OS X] using an X server supports send (what about [Aqua] MacOS X Tcl/Tk?), send still does not work ''out of the box'' in standard distributions of [Windows] yet)

   * Features unique to [Microsoft] Windows versions of Tk
   1. [Windows specific Tcl commands]
   1. [[What are the Windows specific extensions - like [registry], etc.]]
   1. [dde] package

   * Features unique to Apple MacOS X versions of Tk
   1. [[What are the MacOS X specific extensions]]
   1. The [resource] command

   * Features which work differently 
   1. Native widgets on Windows/MacOS X vs [Unix] Tcl and [C] widgets [[is there a [wiki] page detailing which of these exist]]
   1. menu unpost is documented to not work on windows
   1. [[wm attributes]] takes different values on Windows/MacOS, and does nothing on Unix (in [Tcl/Tk] 8.4.9.0, at least).
   1. Icon support in [wm].
   1. Mouse wheel bindings.
   1. "Right" mouse [button] bindings - Mac users expect "context" menus to work with Control-Button-1; Button-3 seems to be the mouse wheel, if a three-button mouse is connected.
   1. The [file] command, especially with directory separators/network drives/etc.
   1. The [exec] command has different forms on different platforms, and works slightly differently
   1. [glob] (with regard to directory separators)
   1. The [tcl_pkgPath] variable is '''missing'''(!!!) in the Windows version of Tcl.  I have no ideea why people would intentionally do such a thing. 

Something probably belongs on this page about key names and behaviors - keys like ` have different names on different platforms I believe.  Perhaps there
are other keys with the same issue?
