Mac: Make Command-1 create a window if none is open

Please make the following keyboard shortcuts work on a Mac (the order is based on the items in the menu item):
Command - 1 go to (or create) the folder window
Command - 2 go to (or create) the profile window
Command - 3 go to (or create) the chat window

Start by locating the Mac menu-item and keyboard-shortcut handling for the folder, profile, and chat windows. Check how each window is selected or created when absent. Done means Command-1, Command-2, and Command-3 each focus the corresponding existing window or create it when none is open.
