The TADJ command adjusts the tab level for the specified range of text.
 The SET TAB value determines the tab size. The tab level is adjusted by
 the value of count; it is incremented for a positive count and
 decremented for a negative count.  A count not preceded by + or - is
 assumed positive.  The TADJ tab setting is the product of the tab size
 and the count.

 Format: [+|-][count]TADJ[+|-][count]entity

 Note that the + or - that precedes the first count is not used to modify
 the direction of entity selection.  Its function in this command differs
 in this way from all other nokeypad commands that use a similar format.
