Best Answer
You can easily vary the command
\doverline
defined below by changing the vertical offset (e.g.0.5ex
).Ti*k*Z
is a mighty tool which allows those quick definitions without digging in to the core ofTeX
.EDIT: egreg's solution is more concise when dealing with subscripts and superscripts. My solution could be adopted to this by using
LuaTeX
's access to\mathstyle
but as his solutions already deals with this issue there is not really a need for it.There is another solution on How to reduce the vertical space between two overlines?.
