HTOP I/O Display

[Stephen Morris]

Hi,
     With the IO tab in HTOP, how do I determine which devices it is 
monitoring and how do I change it to look at multiple volumes?
     While KDE is still thrashing my hard disks after the desktop 
displays (the hard disk light is permanently on, not flickering) HTOP is 
telling me the R/W%, R% and W% are 0 for every process it has listed, so 
it is not looking a the right device for me to determine what is 
thrashing my drives.

While on the subject of HTOP internals, at the bottom of its screen 
it shows a list of keyboard shortcuts, one of which is F10 for Exit. The 
issue I have with that is Konsole has taken over that shortcut for its 
menus, hence it doesn't work in HTOP. How do I change that?

regards,
Steve
