I'm looking at xcode keyboard shortcuts. Some of the symbols used in the list are not on my keyboard. I can't draw there here but I can describe them: 1. A clock timer symbol (a circle with an opening on the upper left with an arrow pointing out) 2. A modified back slash with a minus sign in the upper right 3. Left/Right arrow boxes with an x in the center 4. Up/Down arrows with two horizontal lines through the tail Does anyone know what these characters are?
