Add Insert Sortable Date command. This will insert a string of the form "yyyy-mm-dd", representing today's date, at the current location or replace the selected text. A common use case is to quickly prefixing the title of a new page with today's date so you can easily identify and sort your pages by date.
This command is bound to the keyboard shortcut Ctrl + Shift + D
