Hello, I've recently bought a Mac and I have no idea how to do the following: 1) In Windows Explorer, you can easily create, say, an empty text file (New > Text Document). When I right click in the Finder, I can create a new folder (New Folder) but there's no menu item for creating empty/blank files. How can I do that in Finder? 2) If I have only one Finder window open and attempt to close it (Close button or CMD+Q), the computer beeps and doesn't allow me to close it. Why? I have to minimize it to get rid of it. 3) When a dialog window appears - say a dialog window with "Don't save", "Cancel" and "Save" buttons - how can I quickly control/press the buttons using the keyboard? The only thing I've figured out so far is that pressing Enter is the same as clicking the button which is displayed in blue. 4) How can I set the view settings for all folders in the Finder at once? E.g. when I choose Arrange by Kind, it affects only the currently displayed folder. Any suggestions are welcome, thanks in advance!
