Create macro and create directory inside Emacs 23

These are little notes for my hard head:

1) Create an save a macro:

C-x (   Starts "recording" the macro
C-x )   Ends macro

C-x C-k n  assign a name for the last macro recorded.
M-x  macro-name  execute macro

2) Create a linux directory inside emacs:

M-x make-direct [RET]
