To do this:
a> type number and terminatory ex: 1)
b> start recording using <ALT>qa  . This will record the macro in a.
c> yank the line with yy
d> goto next line
e> press <CTRL>a to increment the number
f> End the macro recording with q
g> Play the macro with numner of times to repeat the actions. Example press 11@a
