+    
+    Attributes:
+        STR (dict): A dictionary mapping short keys to translated message strings.
+                   Keys are abbreviated for brevity but remain descriptive.
+    
+    Usage:
+        Import this class and access messages using the dictionary:
+        `Msg.STR["sel_tl"]` returns the translated "Select tunnel" message.
+    
+    Note:
+        Ensure that gettext translation is properly initialized before
+        accessing these strings to ensure correct localization.
