Most oddly useful Mac shortcut I’ve created for myself recently, copy current date & time to the clipboard so I can paste it in anything:

Result looks like this:

screen shot that shows the information pane in apple shortcuts for this shortcut showing "pin in the menu bar" checked and "use as quick action" checked and under that "services menu" checked and "run with: shift + alt + command + T" key combo

Date shortcut (without the timestamp): https://www.icloud.com/shortcuts/f953008ab67b47bd9d9831954f987b1d
