Shortcut information for this menu item. Should be an object with the following keys: the text that should be used for the shortcut (using the 'text' key), the list of keys that should be pressed (using the 'keys' key) and flags for each key modifier (the 'altKey', 'ctrKey', 'metaKey' and 'shiftKey' keys). For example: { keys: ['B'], metaKey: true, text: '⌘B' } In case there should be different shortcuts for different operating systems, the shortcut object should instead have a key per os with the original shortcut information explainged above. The 'defaultShortcut' key should be used to specify the same shortcut information for the operating systems that weren't specified. An example of this usage: { macintosh: { keys: ['B'], metaKey: true, text: '⌘B' }, defaultShortcut: { ctrlKey: true, keys: ['B'], text: 'Ctrl + B' } }
