With Ubuntu [and probably other distros too] If you have foobar under Wine playing on a computer and a wireless keyboard you use as a handset this is fun >>>
➊ sudo apt-get install winbind
to facilitate processes
➋ sudo gedit ~/.config/openbox/lxde-rc.xml
➌ CTRL+F to find where "keybind key" starts on page
➍ Create a new <keybind key> </keybind> this way
#foobar
<keybind key="A-f"><action name="Execute"><command>wine ~/.wine/dosdevices/c:/"Program Files (x86)"/foobar2000/foobar2000.exe /playpause</command></action></keybind>
<keybind key="C-0"><action name="Execute"><command>wine ~/.wine/dosdevices/c:/"Program Files (x86)"/foobar2000/foobar2000.exe /command:Up</command></action></keybind>
<keybind key="C-9"><action name="Execute"><command>wine ~/.wine/dosdevices/c:/"Program Files (x86)"/foobar2000/foobar2000.exe /command:Down</command></action></keybind>
Nota Bene: if you want other settings use:
Modifier keys
S Shift key
C Control key
A Alt key
W Super key (Usually bound to the Windows key on keyboards which have one)
M Meta key
H Hyper key (If it is bound to something)
➎ then run
openbox --reconfigure && lxpanelctl restart
to validate the changes
NOW: Take your wireless keyboard sit away from computer hit Alt+F to playpause or Ctrl+0 or 9 to see the volume cursor move
