AdderView USB Installation and Use Page 21
3.5 Keyboard hotkey control (model AV4USB-PC only)
The AdderView may be conveniently controlled by pressing keyboard hotkey
combinations on the keyboard attached to the PS/2 style keyboard port (see figure
4). All of the hotkey control commands are invoked by holding down the two hotkeys
and then pressing a command key. By default, the two hotkeys are ‘CTRL’ and
‘ALT’, although other combinations can be selected (see section 2.4.4). Once the
hotkey command has been activated you will need to release the hotkeys and the
command key before a new hotkey command is accepted by the AdderView.
HOTKEYs + TAB is an exception and this allows you to 'tab through' the ports by
holding down the hotkeys and repeatedly pressing TAB.
