Hello, as the subject says, is there a way to undo the previous command or typing in EMACS? Can it be done by using macros?

Thanks in advance,
Ever tried "ESC-x undo" ? :-)

to undo the last three commands.
------
To be precise, C-_ undoes *changes* not commands. A change
is an insertion, deletion, or replacement. Undoing continues up to
the next undo-boundary, which usually, but not always, coincides
with the effect of a single command.
For more info, see the Undo section of the GNU Emacs Lisp Reference Manual.
