/**
 * e_content_editor_selection_save:

 *
 * Saves current cursor position or current selection range. The selection can
 * be later restored by calling e_content_editor_selection_restore().
 *
 * Note that calling e_content_editor_selection_save() overwrites previously saved
 * position.
 *
 * Note that this method inserts special markings into the HTML code that are
 * used to later restore the selection. It can happen that by deleting some
 * segments of the document some of the markings are deleted too. In that case
 * restoring the selection by e_content_editor_selection_restore() can fail. Also by
 * moving text segments (Cut & Paste) can result in moving the markings
 * elsewhere, thus e_content_editor_selection_restore() will restore the selection
 * incorrectly.
 *
 * It is recommended to use this method only when you are not planning to make
 * bigger changes to content or structure of the document (formatting changes
 * are usually OK).
