\section{Frames}
\subsection{Title and Footer}
\begin{frame}[t]{Title}{Subtitle}
    % Bei Frames mit Option \texttt{[t]} werden die Inhalte nicht vertikal zentriert, sondern an der Oberkante begonnen.
	With frames with the option \texttt{[t]}, the content is not vertically centered but started at the top edge.
\end{frame}

\begin{frame}
	With frames without a title, the free space for title can be used for content.
\end{frame}

\begin{frame}[plain]
    % Bei Frames mit Option \texttt{[plain]} werden weder Kopf- noch Fußzeile angezeigt.
	With frames with the option \texttt{[plain]}, neither header nor footer are displayed.
\end{frame}

\subsection{Grid Page for Hand-written Notes}
\begin{frame}{Notes Page with Grid Lines}
	The command \texttt{$\backslash$pagesNotes\{<label>\}\{<subtitle of the note page>\}} can be used to create a page with grid lines for notes, shown on the next slide. \\
	\texttt{$\backslash$refnotes{<label>}} creates a symbol linked to the page with notes. \\
	Let's learn more about entropy! \refnotes{note1}\\
	Let's learn more about divergence! \refnotes{note2}
\end{frame}
\pagesNotes{note1}{Entropy}
\pagesNotes{note2}{Divengence}

\subsection{Footnotes}
\begin{frame}{Footnotes}
	\begin{itemize}
		\item This is a normal footnote\footnote{This is a normal footnote.}.
		\item \texttt{$\backslash$nomarkfootnote} creates a footnote without a mark in the text\nomarkfootnote{This is a footnote without a mark.}.
		\item This is another normal footnote\footnote{This is another normal footnote.}.
	\end{itemize}
\end{frame}

\section{Other Tips}
\subsection{Citations}
\begin{frame}{Citations in Footnote using BibLaTeX}
  Citations in beamer were often dealed bypasting the full text. \\
  The biblatex package enables citing from your .bib file. \\
  Here are several examples of usage:\\[-.5em]
  \begin{itemize}
	\item Cite full text in footnote \footfullcite{Rode23ECOC} by \texttt{$\backslash$footfullcite}.
	\item If the mark is not wanted, combine \texttt{$\backslash$nomarkfootnote} and \texttt{$\backslash$fullcite}. \nomarkfootnote{\fullcite{Rode23JLT}}
 	\item Cite author and year in text \citeauthor{Rode23JLT}, \citeyear{Rode23JLT}.
  	\item Cite title in text \citetitle{Karanov18JLT}.
	\item Use \texttt{$\backslash$supercite} to cite the alphabetic bibkey \supercite{li2018achievable,Karanov18JLT}.
\end{itemize}
\textit{\footnotesize For more usage please refer to \href{http://tug.ctan.org/info/biblatex-cheatsheet/biblatex-cheatsheet.pdf}{\textcolor{kit-blue}{Biblatex Cheat Sheet}}.}
%   \vspace{-1em}
%   You can print all references that are cited at the end of presentation, as shown in the next slide.
\end{frame}

\begin{frame}{Cite in \emph{CEL} Style}
% 	% Cite the reference in text by 
	Cite the in text by \texttt{$\backslash$citereference\{\textcolor{kit-green}{<bibkey>}\}}. 
E.g., 
 	\begin{itemize}
 		\item End-to-end learning applied to optimize multidimensional constellations for IM/DD links~\citereference{Karanov18JLT}
 		\item End-to-end learning of transceivers for the nonlinear Fourier transform~\citereference{gaiarin2020end}
 		\item Constellation optimization for the zero-dispersion channel~\citereference{li2018achievable}
 	\end{itemize}


	Then add the references at the bottom of the page by \texttt{$\backslash$addreference\{<bibid>\}} for single reference, or \texttt{$\backslash$addreferences\{<bibid><bibid>...<bibid>$\backslash$stoppreferences\}} for multiple references.
	\bigskip

% \end{frame}

\subsection{Handout Mode}
\begin{frame}{Handout Mode}
	Handout mode is activated by the option \texttt{handout} in the document class.\\
	A frame with multiple animated slides will be shown on one slide in the handout version.\\
	One can still control the number of slides of one frame in the handout version, e.g.,
	\begin{itemize}
        \only<1|handout:0>{\item One: This will not be shown in the handout version.}
        \only<2-|handout:1->{\item \textcolor{red}{One:} This is shown on the first slide of this frame in the handout version.}
        \only<1|handout:0>{\item Two: This will not be shown in the handout version.}
        \only<2-|handout:1->{\item \textcolor{blue}{Two:} This is also shown on the first slide in the handout version.}
		\item<only@3|handout:2>{Three: This is shown on the second slide in the handout version.}
		\item<only@4|handout:2>{Four: This is also shown on the second slide in the handout version.}
    \end{itemize}
\end{frame}

\subsection{Macros}
\begin{frame}{Predefined Macros}
	\begin{itemize}
		\item \schlagwort{Schlagwort} for highlighting keywords

	Math macros
	\begin{itemize}
		\item \texttt{$\backslash$coloneq} $\coloneq$ for defining a new variable, e.g., $a \coloneq b + c$

		\item \texttt{$\backslash$ceil$\{\cdot\}$} $\ceil{x}$ for ceiling function, e.g., $\ceil{3.14} = 4$
		\item \texttt{$\backslash$floor$\{\cdot\}$} $\floor{x}$ for floor function, e.g., $\floor{3.14} = 3$
		\item \texttt{$\backslash$dd} for differential operator, e.g., $\int f(x) \dd x$, $\frac{\dd f(x)}{\dd x}$
		\item \texttt{$\backslash$real} $\real$ for real part, e.g., $\real(z)$
		\item \texttt{$\backslash$imag} $\imag$ for imaginary part, e.g., $\imag(z)$ 
	\end{itemize}
\end{frame}

\begin{frame}{Math Macros (Cont'd)}
	\begin{itemize}
		\item \texttt{$\backslash$sinc} $\sinc(x)$ for sinc function, e.g., $\sinc(x) = \frac{\sin(\pi x)}{\pi x}$
		\item \texttt{$\backslash$rect} $\rect(x)$ for rectangular function, e.g., $\rect(x) = \begin{cases} 1 & |x| \leq \frac{1}{2} \\ 0 & \text{otherwise} \end{cases}$
	\end{itemize}
	Math symbols:
	\begin{itemize}
		\item \texttt{$\backslash$cA, $\cdots$} $\cA, \cB, \cC, \cdots$ for calligraphic letters
		\item $\0, \bm{n}, \bm{\alpha}, \bm{M}, \bm{\cM}$ for bold math symbols
		\item $\bbN, \bbR, \bbZ$ blackboard bold symbols for the sets of natural numbers, real numbers, and integers, respectively
		\item $\F, \Fq, \Fqm$ for finite field
		\item $\sfA, \sfB, \sfC, \cdots$ sans-serif math letters, usually for naming instead of parameters in notations
