Usually options are typeset similar to

    -p

    Potrzebie mode ...

So search for it, e.g.,

    /^ *-p

The caret regex anchor matches at the beginning of line, and the Kleene star matches zero or more of the previous pattern. In English, the above pattern reads “match -p only when it occurs as the first nonblank characters on the line.”

The surrounding context may be different, so adapt your search pattern accordingly.
