// jumpToChannel - Jason Parekh <jasonparekh@gmail.com> - 06/23/2004
//
// The way this works is if you enter a digit, it will set a timer for 2.5 seconds and enter
// jump to channel mode where as you enter digits, it will find the closest matching channel
// and show that on the program guide.  Within the 2.5 seconds, if you press the button bound
// to END, it will cancel channel jump mode and revert to the highlighted channel before entering
// this mode.  If you let the timer expire, it will stay on the selected channel.
//
// The positioning for the channel display can be in either one of two ways.  To ensure compatibility
// with themes, I made it so if it can't find a specific jumptochannel container, it will use the date's
// and just overwrite the date whenever it is in channel jump mode.  However, if there is a jumptochannel
// container, it will use that.  An example container is as follows:
//
//     <container name="jumptochannel">
//     <area>20,20,115,25</area>
//     <textarea name="channel" draworder="4" align="right">
//         <font>info</font>
//         <area>0,0,115,25</area>
//         <cutdown>no</cutdown>
//     </textarea>
//     </container>
