It would be better to try reserving keys on the `M-s' prefix for commands
similar to normal command but that are isearch specific.  For instance,
`M-w' normally saves the region to the kill ring, so `M-w M-e' could
save the search string to the kill ring.  But this is also possible
with `C-SPC C-r C-r M-w' (i.e. set mark with quiting isearch, go back
to the beginning of the previous search string and copy it).

So perhaps we should bind `M-s M-w' to a more frequently used
command `isearch-forward-word'.  The same could be done for `M-s M-o'
(`isearch-occur') as well:
