After tonight’s TC Lispers Meeting, I had a renewed interest in figuring out why C-<right arrow> didn’t work for me in Org-Mode or Paredit.
After a whole bunch of running in circles, I have discovered a combination that works (with these clues). I have my TERM variable set to xterm-color. I configured the Terminal.app using its Keyboard settings to have it send the string “\033[1;5C” for C-<right arrow> and “\033[1;5D” for C-<left arrow>. (The “\033” is the escape key.)
This works for me even through screen.
Bonus.
