How do I capture Btn3Down or Btn3DblClick on Xbae

[Dhanapalan, Kumar]

How do I write a translation for Btn3Down or Btn3Double Click on Xbae

I wrote some thing like 
XtOverrideTranslations(grid,
                           XtParseTranslationTable(
                        ":<Btn3Down>: SelectCell(Set X)"));

for Btn3Down. But it did not work.

What did I do wrong here.

Thanks
Kumar
