Highlight/color a part of text in block in beamer

Question

I am using beamer in Latex to make a presentation. I use a block for definition like:

 \begin{block}{P1}
 \justifying
  Some text here
 \end{block}

Let us say I wish to highlight a word "Some". By highlight, I mean something like which is performed by \hl{text}. However, hl does not work in a block in latex. So what should I do, if I want to highlight text in block in beamer.

I don't want to change the color of text but I want to highlight it as shown in attached image. alert changes the text color. hl does not work in a block. So how should I do it?

Hello, did you consider using the \alert{text} command which colors your text using the colors defined by the beamer theme ? — Juklaa, Nov 19 '18 at 12:13
@JCoulet alert changes the text color, but I want too highlight it like a marker does. I have edited the question to show what exactly I want — ShJ, Nov 19 '18 at 14:47
Did that image come out of Cool Text Highlighting in LaTeX? That's a neat one! Still, if soul's \hl does not work in your case, most of those answers will also not work, for they rely on soul. — gusbrs, Nov 19 '18 at 15:10

You can apply the answer https://tex.stackexchange.com/a/41693/36296 to your problem:

\documentclass{beamer}

\usepackage{soul}
\makeatletter
\let\HL\hl
\renewcommand\hl{%
  \let\set@color\beamerorig@set@color
  \let\reset@color\beamerorig@reset@color
  \HL}
\makeatother
\begin{document}

\begin{frame}
 \begin{block}{P1}
  Some \hl{text} here
 \end{block}
\end{frame}

\end{document}

Is it possible to change the color of highlighter, which is yellow here to some other color? – ShJ Nov 19 '18 at 15:21

@ShiS Have a look into the documentation of the soul package http://texdoc.net/texmf-dist/doc/latex/soul/soul.pdf – samcarter_is_at_topanswers.xyz Nov 19 '18 at 15:23
If possible, can you direct me to a specific page where it is given in this document – ShJ Nov 19 '18 at 15:25

@ShiS start with the "Short introduction and common rules" section – samcarter_is_at_topanswers.xyz Nov 19 '18 at 15:27
@samcarter could you also briefly explain why \hl{...} does not do the job on its native format? (Out of curiosity ofc) – Raaja_is_at_topanswers.xyz Nov 19 '18 at 19:24

@Raaja I think a quote from the answer I link to explains it pretty good: "beamer redefines nearly anything" :) – samcarter_is_at_topanswers.xyz Nov 19 '18 at 20:44
@samcarter I will go through that link then ;) – Raaja_is_at_topanswers.xyz Nov 20 '18 at 06:48
Worked for me. Thank you! – Md Amiruzzaman Sep 29 '23 at 11:49

If you can compile your document with lualatex, you could hightlight the text with the lua-ul package:

% !TeX TS-program = lualatex
\documentclass{beamer}
\usepackage{luacolor}
\usepackage{lua-ul}
\begin{document}
\begin{frame}
 \begin{block}{P1}
  Some \highLight{text} here
 \end{block}
\end{frame}
\end{document}

To highlight just a few words in beamer one can use \colorbox{yellow}{text}. This does not require extra packages or LuaLaTeX.

\documentclass{beamer}
\begin{document}
\begin{frame}
    \begin{block}{P1}
        Some \colorbox{yellow}{text} here
    \end{block} 
\end{frame}
\end{document}
