Hi,
  I have a question about keysym.  What I am using are DECStation 3100 and 
DECWindow.  As I know my keyboard just has Delete key but no BackSpace key,
I tried to redefine Delete key to something else instead of delete a character
following the cursor.  What I did was this :
	
	void	echo_char();
	static  XtActionsRec actionsTable[] = {
		{"echo_char", echo_char},
	};
	static  char defaultTranslations[] = "<Key>Delete: echo_char()";

			:
			:

	XtAppAddActions (app_context, actionsTable, XtNumber(actionsTable));
	trans_table = XtParseTranslationTable (defaultTranslations);
			:
			:
	textw = XmCreateTextField ( ....... )

	XtOverrideTranslations (textw, trans_table);

It never worked,  but after I changed

	static  char defaultTranslations[] = "<Key>Delete: echo_char()";
to                                                 ^^^^^^
	static  char defaultTranslations[] = "<Key>osfDelete: echo_char()";
						   ^^^^^^^^^
then it worked.  I checked the file (VirtKeys.c) under lib/Xm, seems to me OSF
people defined osfDelete as <Key>DRemove for DECWindow.  So I tried to use 
<Key>DRemove in my statement but it still won't work.  I am pretty confused 
by these key symbols.  Could anyone tell me what's the difference between 
"Delete" and "osfDelete" and where I can find the documentation ?  Any help is
very appreciated.
