My current drivers for my laptop have Fn-f2 through Fn-f6 set to mute, volume up/down and brightness up/down. I also had specialized media keys on a normal keyboard on my PC. I was wondering if there were drivers or anything that could allow me to do things like play/pause the Zune software, or skip to the next song, or skip to the next video in the playlist in MPC. Any ideas?
None.
In MPC:
Ctrl + VK_Next is the default for the next in the playlist. Just change it to something you can use if you don't have a next virtual key.
In Winamp:
There's global hotkeys for controlling music.
I don't know how zunes work, but if you can't use explorer to transfer files, then it automatically sucks and I feel sorry that you got stuck with an inferior product.

My Logitech keyboard had a media button that usually worked; it would pick whatever I was using to play music (worked with Songbird and Zune) and skip to the next song. Hoping for something like that. I completely forgot about the MPC hotkeys, though, thanks.
None.
You can use something like autohotkey to get VK_Next and those virtual keys, but you'll have to set it up properly, and always have it running.

Hrrm. That sounds more technical than I want to get with this. Well, thanks. Don't want to start writing autohotkey scripts. <_<
None.
It's literally a line:
ctrl+num7 = vk_next
or something like that. I haven't used AHK for a while.
If you don't have the actual next button, then you have to set up a hotkey to use it.
