find action by shortcut?

Is there a way to find a particular action from its keyboard shortcut?

In my Mac, Shift-F4 will open the current editor tab in a separate window, which is handy when the editor is divided and you'd like to see one particular file temporarily in the screen full width, but I'm trying to find the name of the action to set it up as well at work on Monday (linux there, so the shortcut will probably not match), but can't find it.
