This is a handy method devised by me to close and eject cd/dvd drive with help of keyboard shortcuts in windows Xp.
To create shortcuts follow these simple steps:
1. Download small freeware utility called tooler.
2. Start up the tooler and create shortcuts for ejecting and closing the cd/dvd drive on the desktop.
3. Now right click on the shortcuts created on the desktop and define keyboard combinations for these shortcuts as shown in image below.
4. Now assign Ctrl+Alt+E for ejecting the drive and assign Ctrl+Alt+C for closing the drive.
