Indeed, sorry.

It should be deactivated while the Mode_switch is hold.  I.e. it should
work like Shift, if you like.  Otherwise there's little point in it, since
I could just press `C-\' twice as well with not so much more trouble.  When
it works like a modifier, I can keep on typing as normal, while switching
to a different layout significantly disrupts the process.
