There is no shortage of hotkey programs for Windows, many of them of high
quality. And of course Windows itself allows you to define hotkeys.
However, a hotkey program in Tcl is not only very simple to write,
it offers the full flexibility and power of Tcl
behind it. Meaning what exactly? Read on.
There are times during software development when you want to run
in interactive mode with
maximum privileges on a system, be God as it were. One might think
running as Administrator would do it but it doesn't.

on Windows, you have to run under the LocalSystem
It is easy enough with Tcl and this post shows you how.
As a side bonus, it also describes how to inject processes into the interactive
user's desktop to run under the user's account as well.
One of the strengths of Tcl
is the ease of integration with other software, whether they
be COM components, libraries or even executable programs that
are not designed for interaction with other programs. Here we look
the facilities Tcl offers related to the last of these --
running external programs and optionally
interacting with them using standard I/O mechanisms.
