Saving macros

To save a macro into ~/.emacs so that you will always be able to use it, make ~/.emacs the current file and do

  M-x insert-kbd-macro RET <macroname> RET

This will convert the macro into Lisp for you. Doing

  M-x 4 insert-kbd-macro RET <macroname> RET

will save the relevent key bindings too.
