Each matrix has its own sorting order for characters. By default the order is that in which the characters were added to the matrix. However, project members may arbitrarily reorder characters in a matrix using the matrix editor or in the character editor. The matrix editor is described in the section called “Changing the order of characters”. The character editor supports two methods to move characters: by dragging and dropping characters in a list or by selecting characters and using the "move char" button to specify, by number, which character the selected characters should be moved under. Either method will support the movement of both single characters and blocks of characters. To select a single character simply click on it once. Selected characters will turn blue (as shown in the figure below). To select a block of characters, click on the first character in the block, then with the shift key on your keyboard depressed, click on the last character in the block.
Once you have selected the desired character(s), click on the "move char" button which will bring up a window asking for the number of the character under which you wish to move the selected characters. If you are moving your selection across a large set of characters this method will be the most convenient. For shorter moves, you may also click on and drag your selection in the list.
