On-Line Notes
Occasionally there are situations when you want to learn information about a
function key or field without having to take the time to look up the information
in the manual. Other times you want to know the purpose of a function key when
the name of the function key legend is not obvious. The on-line notes system is
designed to address these problems.
The on-line notes system provides information in the form of brief, quick-access
notes. Two types of notes are available: Field notes and Key notes. The Notes
text appears on the menu in a small window. You call the notes by selecting the
Notes button at the bottom of the menu or by pressing the Help key on the
keyboard.
A Field note gives you a brief, on-line description of the field (or individual
selection, in the case of an opened select field) where the cursor currently
resides. A note is available for each menu field and selection, but only displays
when you select the Notes button. The note disappears when you press the
Esc key or press the left mouse button while pointing inside the thin message
window (displayed directly above the function key legends). If you press any
other key (except function keys), the note disappears and the key works as usual.
A Key note describes what happens when you press any currently active function
key. If a function key legend does not give you enough information, a Key note
is available to provide more detail. A Key note appears when you select the
Notes button and then select a function key; the note disappears when you press
the Esc key. If you press the function key a second time, its function will be
activated. If you press any other key (except another function key), the note
disappears and the key works as usual.
Try using the on-line notes with the Diagnostic menu and the fields in the Set
Date/Time overlay.
