I accidentally inserted a double left angle quote («) this morning, which lead me to discover that OS X provides a handy way to insert it and of course it’s match, the double right angle quote (»). This may not sound like much, but given how often I use these characters (especially ») in my wire frames and other docs, these shortcuts will noticeably improve my efficiency.
Here are the keyboard shortcuts to use in OS X:
Double Left Angle Quote («) – ALT \ (hold the ALT key and press the backward slash key)
Double Right Angle Quote (») – ALT SHIFT \ (hold the ALT and SHIFT keys, then press the backward slash key)
Note 1: this doesn’t insert the HTML equivalent of either character (« and » respectively), it inserts the actual character as if you were to cut and paste it from the character palette.
Note 2: the ALT and OPTION keys are equivalent. so if you don’t have an ALT key, use OPTION instead.
