With the standard accents: \documentclass{article} \newcommand{\acutedotsym}{% \kern-.2em\'{}\kern-.25em\raisebox{-.15ex}[0pt][0pt]{\.{}}\kern-.05em } \DeclareRobustCommand{\acutedot}[1]{% \leavevmode \vbox{ \offinterlineskip \ialign{% \hfil##\hfil\cr \hidewidth\acutedotsym\hidewidth\cr \noalign{\kern-1ex} #1\cr }% ...


Is this what is meant? \documentclass{article} \usepackage{amsmath,stackengine} \newcommand\acutedot[1]{% \stackengine{.5pt}{#1}{\footnotesize\raisebox{-.8pt}{$\scriptscriptstyle\prime$}% \kern-.8pt.\kern-.3pt}{O}{c}{F}{T}{S}} \begin{document} b\acutedot{e}gu \end{document} Here is one with slightly different metrics, but which works across [most] ...


It depends on the meaning of what you want to write. This is a matter of pure semantics. You have two options: If the « hat » means « matrix M », then the hat is not part of the name of the matrix. It just says that M is a matrix. In this case, you should use \hat{\mathbf{M}}. However, if you call the matrix « M̂ », that is, the « hat » is actually a part ...


Users looking to make common accents in regular text mode can do so with, for example, \'e. MWE: \documentclass[10pt]{article} \begin{document} Alfred Land\'e. \end{document} Output:


You can use \vbox{\halign{}} construction for this special case: \def\macroni{\leavevmode\vbox{\offinterlineskip\ialign{\hfil##\hfil\cr \vrule height.03em width.25em\cr\noalign{\kern.13em}\i\cr}}} \let\macronori=\= \def\=#1{\ifx\i#1\macroni\else\macronori{#1}\fi} S\=a\={\i}


Rather than shorten the length of the macron bar, I'd consider inserting a very thin "kern" (non-discardable whitespace) ahead of the \={\i} part. In the example below, I've chosen a kern of 0.5pt; feel free to adjust the width of the kern to suit you needs. Note that the kern is needed only if \={\i} is preceded by another macron-endowed character. ...
