Hello,As some of you already noticed, adding a context menu to a given inset is now easier than ever. You just need to implement contextMenu() and add the corresponding entry in "stdmenus.inc". For InsetCommand derived Insets, the support code is already there so all that remains to do is to create entries in "stdmenus.inc".
Pavel has already implemented a context menu for equation, nice! So unleash your creativity :-) Abdel.
