Please excuse me if this has come up before, or I just don't understand how
translations works (but in either case tell me about it:-).

I tried to add some translations to the Text Widget, in particular I wanted
sequences like Escape,f to have the same action as Meta-f. For simplicity,
let's assume that the original translation table was just

Meta<Key>F:		forward-word() \n\
<Key>:			insert-char()

To this I added (with XtOverrideTranslations) my

<Key>Escape,<Key>F:	forward-word()

and it worked fine, *but* Meta-f and unmodified f *stopped* working, i.e. they
were effectively ignored! After much experimenting, I found that I had to use
all of

<Key>Escape,~Meta<Key>F:	forward-word() \n\
~Meta<Key>F:			insert-char()

for XtOverrideTranslations in order to achieve the desired effect. Is this the
way it is supposed to work, or a bug? If the former, could someone please
explain the logic of the translation manager to me? - Obviously, I think that
the ~Meta and the second translation are redundant.

N.b. I got similar results when replacing the translation table rather than
overriding, i.e. the mininum table I found to work in this case was

<Key>Escape,~Meta<Key>F:	forward-word() \n\
Meta<Key>F:			forward-word() \n\
~Meta<Key>F:			insert-char() \n\
<Key>:				insert-char() 

Thanks In Advance
