Emacs manual, or try C-ha tabs (If you have turned Emacs help on).

Repeat previous command <count> times. For destructive commands as well as undo.
While . repeats the last destructive command, these two macros repeat the second-last and the third-last destructive commands. See Vi Macros, for more information on Vi macros.
In Vi state, these commands help peruse the history of Vi’s destructive commands. Successive typing of C-c M-p causes Viper to search the history in the direction of older commands, while hitting C-c M-n does so in reverse order. Each command in the history is displayed in the minibuffer. The displayed command can then be executed by typing ‘.’.
Since typing the above sequences of keys may be tedious, the functions doing the perusing can be bound to unused keyboard keys in the Viper customization file. See Viper Specials, for details.
