Do we have any way to move the ECL white rectangle bar up and down using the mouse (roller wheel I was thinking)?

Can we set our own keys to move the white rectangle bar up and down if we don't like the ALT-Arrow keys?

Also, what about the rectangle buttons at the top (NORMAL-MENU, RESETS, NON-NORMAL-MENU) and at the bottom (NORMAL, ITEM OVRD, DHKL OVRD, CHKL RESET)?

None of these buttons seem to work for me when I click on them. Are they functional?

Thanks...
