Searches, does not sound like much of a concept. You see, in this
tutorial, you are shown commands up to this point, as well as anything
of programming I know, you learn commands, and type them one by one,
and computer runs them, just simple steps. But a pile of punctuation
symbolxs! This tutorial just showed you this right away, and before
then was all commands, no sense of it for me.

Sure. Anything no more than a dozen lines would do fine.
