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.
