“Line Select Keys”, typically abbreviated to “LSK” in this
manual are the buttons found along the left and right edges of
the bezel. A label, just inside the bezel – adjacent to the
physical LSK, indicates the function of the LSK. Each
functional LSK is backlit. These LSKs function by rocking left
or right on the key. For cases where there is a list of selectable
options, browse the list in either direction by pressing the left or
right side of the LSK.

Function Key and tab are selected. Whenever the bottom half of
the page is not a traditional HSI, the lower edge of the ADI has
a perspective compass and Horizontal Deviation Indicator
(HDI).
