Configuring Buttons and Sockets
BLUELINE
is fitted with three buttons [1,2,3] and two 3.5mm sockets [4,5] for the connection
of external switches, all five of which may be individually programmed for function using the
display [10] and keypad [8,9] inside the flap on the underside of the unit. The following is a
summary of each setting:
•
Left Click.
On Apple devices this function works as Select.
•
Middle Click.
On Apple devices this function works as Home.
•
Right Click.
On Apple devices this function brings up the AssistiveTouch menu.
•
Drag.
Equivalent to holding down Left Click. Convenient when moving items around
on screen on all types of device. May be cancelled by pressing any button or switch.
Unit beeps whenever Drag is engaged or disengaged, if the buzzer is enabled.
•
Delayed Drag.
A short press is equivalent to Left Click but if a button or switch
configured to Delayed Drag is pressed for more than a second, it is latched on (and
the unit beeps, if the buzzer is enabled). Press any button or switch to cancel. Button
3 cannot be configured as Delayed Drag. Note that Apple devices have this feature
built in, so it may be selected in the AssistiveTouch menu instead if preferred. Do
not engage this feature in both places.
•
Double Click.
Gives two short clicks of Left Click (and the unit beeps twice, if the
buzzer is enabled). Generally, not useful in Apple devices, although used extensively
on PCs to open apps and files. Provided to allow users with low dexterity to double
click by pressing one button or switch.
•
Move Right.
Provided to allow users to effect Page Back in apps such as iBooks and
Kindle, especially on tablet devices.
•
Move Left.
Provided to allow users to effect Page Forward in apps such as iBooks
and Kindle, especially on tablet devices.
•
Cursor Speed.
Allows any button or switch to be configured to change the cursor
speed. Alternatively, this may be achieved by pressing and holding Button 3- see
later section. When a button or switch is set to Cursor Speed, each successive
press increases the speed up to maximum and then a further press changes it to
minimum. Each time the speed is changed, the unit emits several beeps with one
beep indicating the slowest speed and four the fastest.
