The XI581/2 display window can show six lines of information at a time. A scroll bar
appears on the right-hand side of the window as shown in the 'Time Programme'

The scroll bar allows you to quickly move through the items in the list so you can
locate the one you want. The number indicates the number of pages being scrolled
using the right and left arrow keys. Use the following keys to scroll (see Table 3).
NOTE:
With an Excel 50 directly connected or accessed via buswide access, the
display varies from that given for an Excel 100/500/600 controller. The left
two-thirds show the MMI information of the Excel 50; the right third shows
text equivalents of the four fast-access keys of the Excel 50 (see example
below).
