As Christan said, if you map something else to Ctrl-\ the Ctrl-\ will
never be actually generated and your window manager won't see it. For
instance, if you add to your vimrc
noremap <F6> <C-\>
noremap! <F6> <C-\>
then save it and restart Vim, when you hit F6 your window manager will
see F6, pass it to Vim, which will interpret it as having the function
of Ctrl-\.

It is not needed to unmap Ctrl-\, you can have several keys for a
single function. If you do
:map <C-\> <Nop>
then Vim won't act on the Ctrl-\ key combo even if the winmanager
doesn't grab it but it will still act on the :noremap'ped F6.

By default, Ctrl-\ calls different functions in C depending on
context, we have no access to those; but if we map something to <C-\>
it will call those same C functions in the same contexts, and the
winmanager will never see a Ctrl-\
