It looks like I cannot use Ctrl+right_arrow to forward word on my c shell. After some effort I found out that the all the key bindings can be found with bindkey command and I get these:

"\306"         ->  forward-word
"\316"         ->  history-search-forward
"\346"         ->  forward-word
"\356"         ->  history-search-forward
"^[[C"         -> forward-char
"^[OC"         -> forward-char
"^[F"          -> forward-word

Any idea what these all mean? It would be AWESOME if you can point me to where I can learn what these characters mean :)

Thanks!

  • My guess is that \3xx is Meta+\0xx, so \346 is Meta-F. – Barmar Feb 22 '13 at 16:05
  • and you guess is based on what? – user1861088 Feb 22 '13 at 16:19

    Based on the assumption that the default bindings are Emacs-like, and 046 is ASCII F. – Barmar Feb 22 '13 at 16:29

As specified in the csh man page, "\nnn" is the ASCII character corresponding to the octal number nnn. The octal (base-8) number in decimal is 198. Barmer is correct, as "F" (ASCII 046, decimal 70) becomes 306 when you set the high bit.

  • what about '[' or '[['? – user1861088 Feb 22 '13 at 17:35
  • '^[' is Control-[, or ESC. The first two aren't meant to be typed literally; various non-printable keys (arrow keys, HOME, END, function keys, etc) generate escape sequences. The last one is ESC-F, which is simply the escape key followed by F. – chepner Feb 22 '13 at 19:39
