Manipulating the Emacs Environment

Retrieve and switch between buffers programmatically.

Manipulate the 'point' and 'mark' using functions like 'goto-char', 'point', and 'point-max'.

Insert text into a buffer programmatically using 'insert'.

Delete text within a buffer using 'delete-region'.

Read the contents of a file into a buffer and write a buffer's content to a file.

Create temporary buffers using 'with-temp-buffer' for safe text manipulation.
