a video. I mapped it to the input-keyword "sub_visibility". This keyword is mapped to the 'v' key on the keyboard. I tested the patch with old-fashioned subtitles, with freetype subtitles and DVD subtitles. Works fine. The patch also includes documentation updates. patch by Uwe.Reder@3SOFT.de git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@7629 b3059339-0415-0410-9bf9-f77b7e298cf2
