array( 'image' => $wgLang->getImageFile( 'button-bold' ), 'id' => 'mw-editbutton-bold', 'open' => '\'\'\'', 'close' => '\'\'\'', 'sample' => wfMsg( 'bold_sample' ), 'tip' => wfMsg( 'bold_tip' ), 'key' => 'B' ), So the access key for the bold button is "B". But it doesn't work. 1.16 and 1.18 tested.
Could you test 1.19?
