Hi
I think you could create it in 2 steeps:
1- Change the file below to create your shortcut
/Applications/Mathematica.app/SystemFiles/FrontEnd/TextResources/Macintosh/KeyEventTranslations.tr
I use it for Use Command + [ or ] to do [[ or ]] for example. There is how
Item[KeyEvent["[", Modifiers -> {Command}],FrontEndExecute[{FrontEnd`NotebookWrite[FrontEnd`InputNotebook[],"[[", After]}]],
Item[KeyEvent["]", Modifiers -> {Command}],FrontEndExecute[{FrontEnd`NotebookWrite[FrontEnd`InputNotebook[],"]]", After]}]],
2- Using some functions like this:
viewNewWindow[expression_] := CreateDialog[expression, Background -> White]
To evaluate the expression in new windows.
Best regard
Murta
