I can't find a way to do this. There's only binding to open an application. But the apps I want to use this on, (chrome, terminal, and finder) are always open. I just want to open a new window in the current work space.
I can Command + Tab then hit Command + N. But Command + Tab can change my workspace if a window of that app is already opened in another work space.
