TAB

 Inserts a tab at the current editing position, according to the current
 tab stops and tab mode.

 o  To set tab stops and tab mode, use SET TABS.  For example, SET TABS
    MOVEMENT makes the TAB command a cursor-moving function, to move to the
    next tab stop.

 o  The default tab settings are EVERY 8 columns, INSERT, and INVISIBLE.
    Tab stops are independent of the hardware settings of your terminal.

 o  To find out the tab stops of the current buffer, use SHOW.

 Keys:  EVE defines the TAB key and CTRL/I.  Redefining either of these
        affects the other as well.
