[Tex/LaTex] Making hats (and other accents) bold


I've been typesetting some equations, and I've found that the default behavior accents like \hat, \bar, \tilde, etc. makes a rather small and easily-missed mark. Is there some way to make the accents stand out more? In particular, is there any way to make them appear in bold (without affecting the letter they are over)?

Best Answer

Here is one solution, albeit cumbersome:

enter image description here

\usepackage{amsmath}% http://ctan.org/pkg/amsmath
$\hat{a}, \bar{a}, \tilde{a}$ \par
$\hat{\mathbf{a}}, \bar{\mathbf{a}}, \tilde{\mathbf{a}}$ \par
$\mathbf{\hat{a}}, \mathbf{\bar{a}}, \mathbf{\tilde{a}}$ \par
$\thickhat{a}, \thickbar{a}, \thicktilde{a}$ \par

amsmath provides the easy font-and-size switching capability via \text. This allows you to use the \thick-constructs inside super-/subscripts.
