ya!
I wouldn't use it without it.
Here's what I programmed!
^+m::Send {Volume_Mute}
^+.::Send {Volume_Up}
^+,::Send {Volume_Down}
^+]::
^+n::Send {Media_Next}
^+[::
^+b::Send {Media_Prev}
^+o::Send {Media_Stop}
^+p::
^+/::Send {Media_Play_Pause}
That sets commands for holding down CTRL, SHIFT, then a key. So CTRL+SHIFT+, makes the system volume go up 5% whether u are in the program or not. It's easy to remember cuz it's also the > key. Volume up, get it? Plus it's near CTRL and SHIFT.
The rest you can piece together. I use these commands all the time so I never need to worry about going back into the MC window to navigate songs, mute, or change volume.
Oh, also, this one:
^+p::
^+/::Send {Media_Play_Pause}
means I'm assigning the PLAY/PAUSE command to 2 keys, the P key and the / key.
MC native commands still work while u are in the window, like CTRL+M will mute. But now CTRL+SHIFT+M will mute also, whether in the window or not. Use it guys!
