1. Don’t use icons, always spell out the key name
   Symbols like ⇧, ⌥, ⌃, and ⇪ are just confusing for those who don't immediately recognize them.
2. Use sentence case for each key
   That is, capitalize the first letter of each key name, even if it's two or more words. E.g., Shift, Down arrow, Command.
3. Use the + sign with spaces between key names
   That is, Control + Shift.
4. Use (on Mac) and (on Windows) when the key names differ
   That is, Control + Shift (on Windows) or Command + Shift (on Mac).

To copy an element, press Command + C.
