avoid using "i" as mnemonic
Last modified: 2013-09-13 00:59:18 UTC
"Message F_ilters" in mailer's "Edit" menu and "_Import..." in "File" menu use "i" as mnemonic. please avoid this as narrow letters should be generally avoided according to HIG.
Based on Hig guidelines 'Also, it is better not to assign access keys to "thin" letters (such as lowercase i or l), .., The underline does not show up very well on those characters in some fonts.' Confirmed the bug
Fixed in head.
