Deleting lines of text

Use the d (delete) subcommand to delete one or more lines of text. After you delete a line, the first line following the deleted line (or lines) becomes the current working line. After a line is deleted, the remaining lines in the buffer are renumbered.

To delete the current working line, enter:
```
d
```
To delete a specific line number, enter:
```
nd
```
where n is the line number.
To delete more than one line, enter:
```
a1,a2d
```
where a1 is the number of the first line and a2 is the number of the last line.
