Whenever I use the new window shortcut in Safari, it creates a new tab instead of a new window. This most likely happens due to my having chosen the setting System Preferences > Dock > Prefer tabs when opening documents: > Always checked.
However, strangely enough, clicking on the menu bar item File > New Window seems to create a new window normally – not a new tab.
Is it possible to create a new tab with the shortcut?
I think I found a command-line solution, opening up the Terminal and typing in the following:
$ defaults write com.apple.Safari ShowStatusBar -boolean true
Several applications including iTunes let you switch views by using CMD +<number>. CMD + 0 will give you the main window. But some applications like iTunes offer different views.
Just try CMD+tab to iTunes and then variate between CMD + 1 to 9 to see which view you like. In the screenshot below you can see the different options for iTunes. Messages only has the option CMD + 0.

In macOS Sierra 10.12.3, by default the keyboard shortcut to open a new window in most apps is ⌘N, however when one changes the default setting in System Preferences > Dock > Prefer tabs when opening documents: from In Full Screen Only to Always the New Window keyboard shortcut is changed to ⌥⌘N.
