+(description (_"Tai Viet input method using the phonetic key sequence using the Tai Son La keyboard layout.
 The phonetic key sequence means that you type a syllable in this order:
   C W? V v? F? T?
 where
   C is an initial consonant,
   W is a label to labializing C ('ꪫ'),
-  V is a vowel (prefix, postfix, or combining),
-  v is the second vowel of a digraph vowel (in that case V is 'ꪹ'),
+  V is a vowel (V1:prefix, V2:combining, or V3:postfix),
+  v is the second vowel of a digraph vowel
+        (in the case that V is 'ꪹ' and v is 'ꪸ', 'ꪷ', or 'ꪱ'),
   F is a final consonant,
-  T is a tonemark (spacing or combining).")
+  T is a tonemark (spacing or combining).
+
+You can type special symbols by these keys:
+  '$' -> 'ꫛ'
+  '#' -> 'ꫜ'
+  '%' -> 'ꫝ'
+  '!' -> '꫞'
+  '@' -> '꫟'
