I am trying to show my students the idea of reducing (cancelling)

I know of the package named cancel, and this works in ERT mode.
I really don’t want to use ERT if I can help it.
Of course, I would like it to work in the maths-display mode.
This is currently supported in LyX. With the cursor inside a math inset,
look on the math toolbar (the one that gives you font choices, relation
symbols etc.) for an icon that looks like the outline of a square with a
hat over it. (The tool tip for it is "Frame decorations".) Click that,
and near the bottom you'll see all the commands from the cancel package
implemented.
