@ -1529,6 +1529,14 @@ void LyXAction::init()
* \li Action: Inserts math objects and symbols.
* \li Syntax: math-insert <ARG>
* \li Params: <ARG>: Symbol or LaTeX code to be inserted.
* \li Notion: When <ARG> is a _single_ math inset with more than one cell
(such as "x_y^z" or "\frac{x}{y}"), the content of cell(0) is
replaced by the current selection (only works if the selection
is in mathed). As an example, if "abc" is selected in mathed,
"math-insert \frac{x}{y}" replaces "abc" with "\frac{abc}{y}",
and "math-insert x_y^z" replaces "abc" with "abc_y^z".
If nothing is selected (or the selection is not in mathed),
math-insert works as expected.
