This is a Tk question and you should look for an answer in the Tk FAQ
or in comp.lang.tcl. (I know that this question has been discussed in
comp.lang.tcl several times and it really should be in the FAQ.)
Anyway, you can hack your own solution in Tcl by changing the bindings
for your entry. I guess this is not trivial if you want to keep all
the default bindings.
