If no search was previously run, open a new search dialog. In
this case, no search is done.
If a search was previously run, the search dialog won't be
shown and the options from the previous search (including the
search pattern) will be used to find the next occurrence
of the pattern. Next is relative based on direction.
Position the window to display the located occurrence in the
text.
Return True if the search was successful and False otherwise.

selected text. If the selected text isn't changed, then use
the prior search phrase.
