How do you bring up the Xbox Music Mini Player?

Some keyboards have an "FN" key. With that FN key you can use secondary functions such as previous, next, stop, play/pause etc. Those buttons will make the mini player popup. I believe that's the only way else to make that pop up.

 

Install Autohotkeys make ahk files using these variables

Code:

{Media_Next} 
{Media_Prev} 
{Media_Play_Pause} 
{Volume_Up}
{Volume_Down} 
{Volume_Mute} 
 

Example for next media file...

Code:

#NoTrayIcon
Send {Media_Next} 

Example for Volume up

Code:

#NoTrayIcon
Send {Volume_Up 5}

 

Use keyboard shortcuts for this.

-On laptop: Use Fn + Function keys (check icons on F1-F10 keys)
-On desktop: Check if your keyboard has multimedia keys. If there are no such keys, then there is no other way except Autohotkeys as suggested by noncentz705
