Hello,

I think that what I really care about is the word on which the oncontextmenu occurred, as can be deduced from rangeParent and rangeOffset (this is what inlineSpellChecking uses). Unfortunately I have been unable to access this information. No matter what attribute I try to access on rangeParent, I get errors like:

Error: Permission denied to access property 'data' from a non-chrome context

Any pointers?
