You may also want to know about:

Global Bindings Starting With M-s:
key             binding
---             -------

M-s h           Prefix Command
M-s o           occur
M-s w           isearch-forward-word

M-s h f         hi-lock-find-patterns
M-s h l         highlight-lines-matching-regexp
M-s h p         highlight-phrase
M-s h r         highlight-regexp
M-s h u         unhighlight-regexp
M-s h w         hi-lock-write-interactive-patterns

As you can see, e.g. M-s h r can be very useful at times.
