+**(179) What are reply templates?**
+
+Reply templates are predefined answer texts.
+
+You can reply with a template, insert a template via the three-dots overflow menu in the message editor,
+and long press on an open space to insert a snippet (the latter requires Android 6 Marshmallow or later).
+
+Templates can have the following options:
+
+* *Default*: template to use when writing a new message
+* *Use as read receipt*: template to use instead of the default read receipt text
+* *Favorite*: template will be added in the main reply popup menu
+* *Snippet*: template will be used as text fragment (since version 1.1857)
+* *Hide from menus*: template will be hidden (disabled)
