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?
