Display Cursors In most cases, the appearance of the cursor indicates what will happen when you press the next key. Cursor Entry INS (insert) 2nd ALPHA "full" Appearance Meaning Solid blinking rectangle The next keystroke is entered at the cursor; it types over any character. Blinking underline The next keystroke is inserted in front of the cursor location. Blinking # (arrow) The next keystroke is a 2nd operation. Blinking A The next keystroke is an alphabetic character. Checkerboard rectangle You have entered the maximum characters in a name, or memory is full. If you press ƒ or y during an insertion, the underline cursor changes to an underlined A or # cursor. If you press y or ƒ on a screen on which there is no edit cursor (such as the MODE screen or a graph), # or A appears in the upper right corner. Graphs and the screens for viewing and editing tables, matrices, and lists have different cursors, which are described in the appropriate chapter. Busy Indicator When the TI.82 is calculating or graphing, a moving vertical bar shows in the upper right of the display as a busy indicator. (When you pause a graph or a program, the busy indicator is a dotted bar.) Operating the TI.82 1-5
