49: Is there an equivalent to the `.' (dot) command of vi? (`.' is the redo command in vi. It redoes the last insertion/deletion.) No, not really, because Emacs doesn't have a special insertion mode. You can type "C-x ESC ESC" (repeat-complex-command) to reinvoke commands that used the minibuffer to get arguments. In repeat-complex-command you can type M-p and M-n to scan through all the different complex commands you've typed. To repeat a set of commands, use keyboard macros. (See "Keyboard Macros" in the on-line manual.) If you're really desperate for the `.' command, vip-mode, which comes with Emacs 19, appears to support it. (Vi-mode, another vi emulator that comes with Emacs 19, does not appear to support `.'.)
