What combination of keys do I press to produce the command symbol (⌘) on Mac OS X?
(I copied the above symbol from http://en.wikipedia.org/wiki/Command_key.)
If you're just looking for the Unicode versions of Mac OS X keys, you can use this site to copy and paste them from the text box.
More generally, Mac OS X provides a pane to insert special characters. You'll typically find it under Edit -> Special Characters in any program that takes text input. The Command key symbol can be found under Symbols -> Technical Symbols. To insert the character, select it and click "Insert".
If you're really hardcore and are looking for a way to type the character by entering the Unicode hex code, this is possible:
2. From the input source selector in the menu bar, select "Unicode Hex Input"
3. To enter a Unicode character, hold down option and type the 4-digit hex code for the character and it will be inserted. In this case, it would be option+2318.
I also found it hard to find a straight answer for this, so I just went into System Preferences > Language & Text > Text and created a use symbol and text substitution option where when I type (cmd) it replaces it with the command symbol.
