\makeslidetitle{\macroname{stepwise} Example: Inside A Paragraph}\label{Sec:ExPar}
%
% We show that \stepwise can be used for highlighting words within a paragraph.
% Furthermore, it is demonstrated how the order in which \step's are executed can be changed.
%
% We define a `placeholder' which will mark the place of missing words (instead of \displayphantom).
%
\newcommand{\placeholder}[1]{\leavevmode\phantom{#1}\llap{\rule{\widthof{\phantom{#1}}}{\fboxrule}}}%
%
% We use the custom command \parstepwise which not only wraps the whole argument of \stepwise into a minipage (because
% otherwise vertical spacing goes haywire, don't ask me why), but also gives substance to steps.
%
% All variants of \stepwise take an optional argument the contents of which are executed inside a group before the
% inner loop of starts. It can be used to set parameters locally.
% Here, we redefine \activatestep (which has been explained in the equation example) to highlight the first
% appearance of any word.
% \hidestepcontents is used as a `wrapper' for those arguments of \step which should not appear yet. It either
% displays nothing (this is the default for \stepwise and \liststepwise) or puts its argument into a \phantom
% (the default for \parstepwise); this behaviour is also toggled by \boxedsteps and \nonboxedsteps.
% Here, we redefine it to use our selfdefined \placeholder to mark `missing' words.
%
\parstepwise[\let\hidestepcontents=\placeholder\let\activatestep=\highlightboxed]%
{%
\begin{quote}
\Huge We can \step{create} a \step{fill-in-the-blanks}
%
% \step takes an optional argument with which it can be specified _when_ its argument is to appear. This is
% expressed in \ifthenelse syntax (see the documentation of the ifthen package).
% Here, we refer to the counter step which is advanced by \stepwise and contains the number of the current step.
% This way, steps can be made to appear in any order.
\step[\value{step}=5]{text} which is then
\step[\value{step}=4]{filled} in in
\step[\value{step}=3]{\textbf{any}} order!

% The \hidetext command hides its argument while respecting automatic line breaks and such. The command needs the soul
% package to work. Read the documentation of soul for restrictions as to what can go in the argument of \hidetext.
