When Ediff starts up, it displays a small control window, which accepts the
-Ediff commands and two or three windows displaying the files to be compared
+Ediff commands, and two or three windows displaying the files to be compared
or merged. The control window can be in its own small frame or it can be
part of a bigger frame that displays other buffers. In any case, it is
important that the control window be active (i.e., be the one receiving the
one of them by typing the region number and then `j'. Typing @kbd{##}
again puts Ediff back in the original state.

instance, if Ediff is merging according to the `combined' policy, then the

+Finally, Ediff can be told to ignore the case of the letters. This behavior
+can be toggled with @kbd{#c} and it is controlled with three variables:
+@code{ediff-ignore-case-option}, @code{ediff-ignore-case-option3}, and
+@code{ediff-ignore-case}.
+
+The variable @code{ediff-ignore-case-option} specifies the option to pass
+to the diff program for comparing two files or buffers. For GNU
+@code{diff}, this option is @code{"-i"}. The variable
+@code{ediff-ignore-case-option3} specifies the option to pass to the
+@code{diff3} program in order to make it case-insensitive. GNU @code{diff3}
+does not have such an option, so when merging or comparing three files with
+this program, ignoring the letter case is not supported.
+
+The variable @code{ediff-ignore-case} controls whether Ediff starts out by
+ignoring letter case or not. It can be set in @file{.emacs} using
+@code{setq-default}.
+
+When case sensitivity is toggled, all difference
+regions are recomputed.
