+# LOCALIZATION NOTE: The property keys ending with ".key" are for access keys.
+# Localizations may add or delete properties where the property key ends with
+# ".key" as appropriate for the localization. The code that uses this data can
+# deal with the absence of an access key for an item.
+#
+# For gbk, gbk.bis and gbk.bis.key are used to trigger string changes in
+# localizations.
+#
+# In the en-US version of this file, access keys are given to the following:
+# * UTF-8
+# * All encodings that are the fallback encoding for some locale in Firefox
+# * All encodings that are the fallback encoding for some locale in IE
+# * All Japanese encodings
+#
+# For the items whose property key does not end in ".key" and whose value
+# includes "(" U+0028 LEFT PARENTHESIS, the "(" character is significant for
+# processing by CharsetMenu.jsm. If your localization does not use ASCII
+# parentheses where en-US does in this file, please file a bug to make
+# CharsetMenu.jsm also recognize the delimiter your localization uses.
