TextLab relieves you of routine operations on alignment of many lines of the text across. Equal left and-or the right text edge is provided automatically. Position of a right edge of the text is usually defined for all text in advance and from a fragment to a fragment varies seldom. Desirable position of a right edge of the text is set in options (Text Witsh parameter).
Position of a left edge of the text (indent) is important and often varying parameter. Before performance of operations of formatting you can set a desirable indent, having established an indent for the first line of the selected text. For other lines TextLab will provide precisely the same indent automatically. I.e. TextLab considers a space of the first line of selected text, as a indent of all lines of selectes text wished for you.
