Alignment area

This area is purposed for visualizing and editing sequences of alignment.

Single left mouse button click over a symbol marks this symbol with color and changes its style to italic, and similar symbols that are in the same positions in all sequences are being marked also.

To move a fragment of sequence press the "Shift" key, place mouse pointer over a symbol, press the mouse left button and then drag a symbol. If to drag a symbol to the right, then a gap will appear in the original position of symbol and sequence will be displaced in chosen direction. If the Edit->Groups editing mode is on, then gap insertion occurs in all sequences of the selected group. If to drag a symbol to the left, then gap symbols will be replaced by the dragging fragment.
