LBL_ClassName has 2 mnemonic key,
LBL_Name_Mnemonic and LBL_Class_Mnemonic.

But in general,
if a message is set several mnemonic letters,
it does not work after translation.
Because, like as follows, a translated message has
only 
one letter as a mnemonic letter.

(Original msg)
Label_Help=Help
Label_Help_mne1=H
Label_Help_mne2=e

(translated msg)
Lebel_Help=<t9ned msg>(H) <-- Can't add all
mnemonic letters.
Label_Help_mne1=H
Label_Help_mne2=e 

A message and a mnemonic letter should be set one
to one.

Please do not reuse LBL_ClassName.
