This TIP proposes adding support for the multimedia keys present on many modern keyboards.
Tk is lacking support for the multimedia keys as described on 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).
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.
The support can be added by extending some keymapping lookup tables in Tk.
A Ticket already exists with a proposed patch https://core.tcl-lang.org/tk/tktview/499526180d6cd5ca7c02eed96c10e9d3630a807c and fvogel has also created a branch https://core.tcl-lang.org/tk/timeline?r=tip-464 .
