|Description||within the Update processor, the cursor is moved using cursor control command sequences each beginning with the control key being depressed.
The cursor is the underline or block which moves around the screen when characters are typed. Cursors have various forms depending on the terminal: highlighted, blinking, reverse video, etc. In all cases, the cursor indicates where the next character typed is displayed on the screen. Cursor movement commands are used to position the cursor anywhere in the item without altering the text. The cursor actually moves on the screen of the CRT, but since the screen is only a window into the item, the cursor may be moved off the screen forcing a screen redisplay (scrolling).
The following list is a summary of the cursor movement commands, see each token for more information.
<ctrl>+b Moves the cursor back a line
<ctrl>+n Moves the cursor down a line
<ctrl>+u Moves forward a word, also used for cruising
<crtl>+y Moves backward a word, also used for cruising
