HP HP-28S - The Command Line; The Cursor Menu

18
The Command Line
The command line holds any number of characters representing ob-
jects in text form. It appears at the bottom of the display (immediately
above the menu labels, if present) when you begin to key in an object
or when you use .1 EDIT I or .1 VISIT I to edit the contents of an exist-
ing object.
The command line can hold more than one row of text. If you enter
more than 23 characters into one row, characters scroll off the display
to the left. An ellipsis ( ... ) appears in the leftmost character position
to indicate the undisplayed characters. If you try to move the cursor
past the left end of the display, the leftmost characters scroll back into
the display, and characters scroll off the display to the right. An ellip-
sis
then appears at the right end of the display. When the command
line contains multiple rows of text, all rows scroll left and right
together.
The Cursor Menu
The cursor menu is a special menu of editing operations. It is active
whenever the command line is present and no menu labels are visi-
ble.
The cursor menu contains both shifted and unshifted keys. The
unshifted keys are labeled in white above the corresponding menu
keys, as illustrated.
