Multimedia Keyboard Programming For Windows 7

I have been using a Vista Computer which came with a multimedia keyboard. The multimedia keys can be easily programmed in the Keyboard item in the Control Panel. This works very well and lets me choose Eudora for the email program and call up the Character Map with the Calculator multimedia Key. Apparently Microsoft thought it would be easier for users to just pick a default program for each multimedia key. This gives the user much much less flexibility and since users have many different interests, flexibility is a great thing to have. In Windows 7 the Control Panel Keyboard item does show a grid like Vista, but the cells in the grid are blank. As near as I have been able to determine, there is no way to use the grid in Windows 7. HP technical support people, both telephone and email,but have not come up with a solution. The problem is made even worse, because I can't make Eudora the default email program, because it doesn't fit the current method of picking defaults. My newest computer is aWindows 7 that came with a multimedia keyboard. I wonder, if there a an acceptable solution I am missing? There was a tile when Microsoft's support was really outstanding and included outstanding documentation.
