Code Used: [rmN] or [rm0]
Keystroke: Accessed from Layout: Right Margin (Shift + F4 may be used to set a margin of 6)
What does it do?
It positions what follows on a new line (if not already on a new line) and sets the right margin for the text. It should be noted that while normal text will "word wrap" at this margin, it is still possible to use Tabulation Codes to place text in the right hand margin. (For example, poetry line numbers)
Where would it be used?
There are occasions when, just as in print, right margin space is required, into which one may add additional information. On the other hand, one may simple wish the place emphasis on a section of text by reducing both the left and right margin.
Usage in DBT:
Our text should now finish in cell 30[<]
[rm5]But now we have set our right margin to five[<]
[ind5]And now our left margin is also set to five
Produces in Braille:
,\r text %d n[ f9i% 9 cell #cj
,b n[ we h set \r "r m>g9
6five
,& n[ \r left m>g9 is
al set 6five
Let us explain:
The [<] code put text on a new line. [rm5] creates a right margin of five cells, while [ind5] begins the left margin in cell 5.
For the Technical:
There are times when you might need to add a second parameter to [rmN].
Most often, this second parameter value will be 0, e.g. [rm4:0] or [rm0:0].
This is necessary to reset the "override margin" back to 0 after it has been increased by the [linenum] command. The "override margin" cannot be reset by [rmN] alone.
