+# Edit Previous Parts Of The Pry Buffer History
+
+Each line of Ruby you enter into a Pry session is recorded with a number in
+the buffer history. Pry keeps this buffer history so that you can recall
+parts of it for editing and subsequent execution.
+
+If you use the `edit` command by itself, Pry will open the previous Ruby
+statement in your default editor. But what if you want to edit a statement
+from a while back? Or even a series of statements?
+
+Use the `--in` flag with `edit` either specifying a single record in the
+buffer history or a range of records.
+
+```ruby
+$ pry
+[1] pry(main)> puts "Hello"
+Hello
+=> nil
+[2] pry(main)> puts "World"
+World
+=> nil
+[3] pry(main)> puts "People"
+People
+=> nil
+[4] pry(main)> edit --in 1..2
+Hello
+World
+=> nil
+```
