Down arrow
key Down arrow
key Moves the cursor down one line toward the bottom of the buffer, regardless of whether ADVANCE or BACKUP is in effect.

9.8.5 Locating Text

The following table describes commands and keys that can be used to locate text:

Keypad Mode Line Mode Nokeypad Mode Description

ADVANCE ADV Sets the direction for subsequent editing work to forward (to the right of the cursor and down toward the end of the buffer).

BACKUP BACK Sets the direction for subsequent editing work to backward (to the left of the cursor and toward the beginning of the buffer).

CLSS Clears the text string currently in the search buffer.

FIND FIND "string"
^@. Searches for specified text.

FNDNXT FIND "" "" Searches for the next occurrence of a string defined by the FIND command.

RESET RESET Cancels the active select range, sets the direction to advance, and sets EDT to the DMOV (default move) state.

	SUBSTITUTE NEXT	SN	Searches for the next occurrence of a string and replaces it with another string. This command uses strings that have been stored in the search buffer and in the substitute buffer.

9.8.7 Moving Text

The following table describes commands and keys that can be used to move text:

Keypad Mode Line Mode Nokeypad Mode Description

APPEND APPEND Deletes the select range (keypad mode) or specified entity (nokeypad mode) from the current buffer and adds it to the end of either the PASTE buffer (the default) or the specified buffer.

COPY Copies the specified text to the specified location. You can copy a range of text from one location to another within the same buffer, or you can copy to and from different buffers, creating new buffers as appropriate. No text is deleted. The /DUPLICATE qualifier enables you to copy the specified text n times.

CUT CUT In keypad mode, removes the active select range from the current buffer and stores it in the PASTE buffer. In nokeypad mode, removes the specified entity from the text buffer and stores it in another specified buffer.

CUT + PASTE MOVE CUT + PASTE Moves lines from one location to another within the current buffer or from one buffer to another. The lines are deleted from their original position and are inserted at the new location.

PASTE COPY
MOVE PASTE Copies or moves text within a buffer. In keypad mode, PASTE copies the PASTE buffer contents into the current buffer. In nokeypad mode, PASTE copies the contents of any buffer into the current buffer.

Keypad Mode	Line Mode	Nokeypad Mode	Description
APPEND		APPEND	Deletes the select range (keypad mode) or specified entity (nokeypad mode) from the current buffer and adds it to the end of either the PASTE buffer (the default) or the specified buffer.

9.8.8 Indenting Text

The following table describes commands and keys that can be used to indent text:

Keypad Mode Line Mode Nokeypad Mode Description

Ctrl/A TC (Tab Compute) Establishes a tab position and resets the indentation level. The indentation level is the number of columns, starting at the left of the screen, that you want to leave blank before beginning a line of text. To use this command, the current cursor position must be a multiple of the SET TAB value.

Ctrl/D TD (Tab Decrement) Decreases the current indentation level count by one setting. The indentation level count is generally set by the Ctrl/A or TC (Tab Compute) command.

Ctrl/E TI (Tab Increment) Increases the current indentation level count by one setting. The indentation level count is generally set by the Ctrl/A or TC (Tab Compute) command.

Ctrl/T TAB ADJUST TADJ (Tab Adjust) Uses the value established by the line-mode SET TAB command to indent lines of text in a select range. Requires SET TAB to be in effect.

SET TAB
SHOW TAB Establishes the SET TAB value for the various tabbing functions (tab compute, tab adjust, tab increment, and tab decrement). SHOW TAB indicates the SET TAB value and the tab indentation level count.

SHL (Shift Left) Moves the entire buffer text eight characters (one tab stop) to the left.

SHR (Shift Right) Moves the entire buffer text eight characters (one tab stop) to the right.

TAB
Ctrl/I TAB Moves text to the right, regardless of whether ADVANCE or BACKUP are in effect. The number of column positions that the text moves depends on the cursor position, the value set by the SET TAB command (if one is in effect), and the indentation level count (if one is in effect).
