There's a very good debugger/inspector for Tcl/Tk/Tix called TixInspect,
which has a basic but fairly useful debugger built into it. The inspector
lets you see
everything, and modify things on the fly - it's very powerful. Look at

	http://tix.sourceforge.net/Tixapps

To use SN with TixInspect under Unix, you'll have to comply with Tk's
semi-rigorous demands for Xauth authentication and no xhosts, or recompile the
tk dynamic library with this turned off. In the Makefile for tk, look for

# To turn off the security checks that disallow incoming sends when
# the X server appears to be insecure, reverse the comments on the
# following lines:
SECURITY_FLAGS = 
#SECURITY_FLAGS = -DTK_NO_SECURITY

Then in the SN code, if it's not already there, add the following line;

	tk appname "SN#[winfo id .]"

To use SN with TixInspect under Windows, you'll have make sure the 
Tcl tcldde83.dll is available either in the directory with with the tcl83.dll
or in lib/tcl8.3/dde1.0 (replace 83 with whatever verion of Tcl you're using).

Then in the SN code, if it's not already there, add the following lines;

	package require dde
	dde servername "SN#[winfo id .]"

TixInspect is the revised updated version of the time-honoured Tkinspect,
and is built for Tix applications such as SN. OTOH, if I had of known you
were going to use it for adding Wordstar bindings, I would never have
released it:-)
