It is easy to insert a list of ascending numbers, for example, this command inserts five lines after the current line: :put =range(11,15) The five lines are: 11 12 13 14 15 If wanted, the lines can be inserted after a particular line number, for example :123put =range(11,15) inserts them after line number 123, while :0put =range(11,15) inserts the lines at the start of the buffer, and :$put =range(11,15) inserts them after the last line. An equivalent command is :call append(123,range(11,15))) to insert the five lines after line number 123, for example.
