TeX - LaTeX Asked on July 9, 2021
Sometimes in beamer I like to use itemize as follows (code largely from https://topanswers.xyz/tex?q=1334):
documentclass{beamer}
setbeamersize{text margin left=10mm,text margin right=5mm}
setbeamertemplate{frametitle}[default][center]
newenvironment{grayenv}{only{setbeamercolor{local structure}{fg=black!15}}}{}
begin{document}
begin{frame}{Frame Title}
setbeamertemplate{itemize items}[circle]
addtolength{leftmargini}{-0.7cm}
begin{itemize}[<+-|gray@+(1)->]
setlengthitemsep{5pt plus 1fill}
item line one
item line two
item<+-> line three
end{itemize}
end{frame}
end{document}
This has the effect of fading out bullet point markers for old bullet points as well as a few other features I find helpful. Notice that the final item has to have <+-> so we don’t get a new slide with all the markers gray.
Is there way to make a new environment myitemize
that would capture all the features of my bespoke itemize environment?
You need to define the command myitemize
based on itemize
command and add your settings inside it and endmyitemize
command same as enditemize
documentclass{beamer}
setbeamersize{text margin left=10mm,text margin right=5mm}
setbeamertemplate{frametitle}[default][center]
newenvironment{grayenv}{only{setbeamercolor{local structure}{fg=black!15}}}{}
setbeamertemplate{itemize items}[circle]
addtolength{leftmargini}{-0.7cm}
newcommand{myitemize}{itemize[<+-|gray@+(1)->]
setlengthitemsep{5pt plus 1fill}
defItem{item<+->}
}
letendmyitemizeenditemize
begin{document}
begin{frame}{Frame Title}
begin{myitemize}
item line one
item line two
Item line three
end{myitemize}
end{frame}
end{document}
