I did not get the [[ ]] created in notebook. This is what I did : on windows, I edited C:\Program Files\Wolfram Research\Mathematica\7.0\SystemFiles\FrontEnd\TextResources\Windows\KeyEventTranslations.tr and copied what you have above to the bottom of file (made sure no typos, and commas betweem last item is there ok, etc.. Saved the file, started Mathematica. I also tried having "x" in place of "<", so I can it just CTRL X to make [[ ]] since it is faster than CTRL < (no need to hit SHIFT key to reach "<"), but again, it did notthing. When I hit CTRL x nothing happens on the screen. Windows 7, 64 bit, Mathematica version 7.0 --Nasser
