The above link seems edifying.

 3.2 Range of Operation, Line Addressing and Marks

 /Section 1/+,/Section 2/-

 - all lines between Section 1 and Section 2, non-inclusively, i.e. the
   lines containing Section 1 and Section 2 will not be affected.

It would appear the 1 (in '/KEY2/+1' and '/KEY1/-1d') is superfluous in
the sense that if you omit the number after + or - it defaults to 1 (one).

Maybe it's better to be explicit.

'd' means delete.

You said text editor so I thought of vim. I used a search engine to look
up how to do it. 

Bah, the latest news, the latest news is not the last.
