This question refers to both enumerate and itemize lists as in the MWE below. If possible, I would like to specify list parameters in standard LaTeX, without invoking any special package. My objective is to manipulate the apparance of a list and escape the default appearance.
For instance, I would like to remove the extra vertical space between items or increase it. I would like to control (e.g., eliminate or increase) the horizontal indentation of second and subsequent lines in each item. If I can do this by learning "well known" LaTeX list parameters, instead of invoking a special package, so much the better.
\documentclass{article}
\begin{document}
In an enumerated list, one might write:
\begin{enumerate}
\item
All work and no play makes Jack a dull boy.
All work and no play makes Jack a dull boy.
All work and no play makes Jack a dull boy.
All work and no play makes Jack a dull boy.
\item
All work and no play makes Jack a dull boy.
All work and no play makes Jack a dull boy.
All work and no play makes Jack a dull boy.
All work and no play makes Jack a dull boy.
All work and no play makes Jack a dull boy.
All work and no play makes Jack a dull boy.
All work and no play makes Jack a dull boy.
\end{enumerate}
Or without numbers, one could say:
\begin{itemize}
\item
Here's Johnny!
This is a famous line and moment in The Shining, with which, of course, that well-known scary photo is associated.
\item
He-rrrre's Johnny!
\end{itemize}
