 ABSTRACT 
==========

 This TIP proposes adding support for the multimedia keys present on 
 many modern keyboards. 

 RATIONALE 
===========

 Tk is lacking support for the multimedia keys as described on 
 <URL:https://msdn.microsoft.com/en-us/library/windows/desktop/dd375731%28v=vs.85%29.aspx> 

   VK_VOLUME_DOWN        0xAE   Volume Down key
   VK_VOLUME_UP          0xAF   Volume Up key
   VK_MEDIA_NEXT_TRACK   0xB0   Next Track key
   VK_MEDIA_PREV_TRACK   0xB1   Previous Track key
   VK_MEDIA_STOP         0xB2   Stop Media key
   VK_MEDIA_PLAY_PAUSE   0xB3   Play/Pause Media key

 Linux supports these as, e.g., XF86AudioPlay, XF86AudioPrev, 
 XF86AudioNext. Tk should support them as well so that application 
 programmers can make use of the keys as appropriate. 

 Because this is driven by changing external circumstances, it is 
 propsed that this TIP be backported to all future-releaseable versions 
 of Tk (i.e., 8.5 onwards). 

 PROPOSAL 
==========

 The table of supported keys should be extended to include the following 
 named keys: 

     * *XF86AudioLowerVolume* - the volume-down key 

     * *XF86AudioMute* - the volume-mute key 

     * *XF86AudioNext* - the next-track key 

     * *XF86AudioPlay* - the start-playback key 

     * *XF86AudioPrev* - the previous-track key 

     * *XF86AudioRaiseVolume* - the volume-up key 

     * *XF86AudioStop* - the stop-playback key 

 The above list does not imply any ordering in the implementation. 

 IMPLEMENTATION 
================

 The support can be added by extending some keymapping lookup tables in 
 Tk. 

 A Ticket already exists with a proposed patch 
 [<URL:http://core.tcl.tk/tk/tktview/499526180d6cd5ca7c02eed96c10e9d3630a807c>] 
 and fvogel has also created a branch 
 [<URL:http://core.tcl.tk/tk/timeline?r=tip-464>].
