Vim switch y and z

Question

Is there a way to teach vim to switch usage of y and z? So for example yy would save a file, ya would toggle etc.. This would be much more usable with my German keyboard layout. What other technique could I use to cope with the problem of "dislocating" my fingers when using vim?

Answer 1

:noremap y z
:noremap z y
:noremap! y z
:noremap! z y

:lnoremap might be necessary instead of :noremap! ... See :help :map and :help mapmode-l.
