The undo command applies only to changes in the buffer; you can't use it to undo cursor motion. - On a graphics terminal (including text-mode frames displayed by a -terminal emulator, such as @command{xterm}), the easiest way to invoke -@code{undo} is with @kbd{C-/}; that doesn't need the Shift key.

Although each editing command usually makes a separate entry in the undo records, very simple commands may be grouped together. diff --git a/doc/emacs/dired.texi b/doc/emacs/dired.texi index 24fd02aac1a..fdc4703e86f 100644 --- a/doc/emacs/dired.texi +++ b/doc/emacs/dired.texi @@ -129,6 +129,17 @@ options (that is, single characters) requiring no arguments, and long options (starting with @samp{--}) whose arguments are specified with @samp{=}. +@vindex dired-switches-in-mode-line + Dired displays in the mode line an indication of what were the +switches used to invoke @command{ls}.
