How to jump to a particular flag in a Unix manpage?

When reading a Unix manpage in the terminal, how can I jump easily to the description of a particular flag?

For instance, I need to know the meaning of the -o flag for mount. I run man mount and want to jump to the place where -o is described. Currently, I search /-o however that option is mentioned in several places before the section that actually describes it, so I must jump around quite a bit.

Thanks.

What I do is put a few blank spaces in front of the flag like so:

/     -o

That's not 100% reliable but you jump through a much less hoops. If you want even better success rate, try "/^ +-o". That would find lines starting with blanks and followed by -o. I wouldn't like to type that weird string often though.

I have defined this function in my .bashrc

function manswitch () { man $1 | less -p "^ +$2"; }

which you can use as follows

manswitch grep -r

I got it from this commandlinefu.

Note: the argument to the -p switch of less is a regexp telling less to look for a line starting with (^) one or more spaces (+) followed by the switch (second arg. so $2), so it has the advantage of working with different formatting.
