The WIRIS editor window is split in two main areas: a tab menu which contains a big number of icons, and an edition area where you can see your current formula, the location of the cursor, and the text currently selected (if any). It also contains an Edit button to make sure you can always access to the cut, copy, paste, do and redo functions. When you are done, click on OK to save changes, or click on Cancel to exit without doing modifications.
Writing text is done just as in any other WYSIWIG editor: you can type keyboard characters, move the cursor with either arrow keys or the mouse, select a portion of contents, cut (CTRL-X), copy (CTRL-C), paste (CTRL-V), undo (CTRL-Z), redo (CTRL-Y), delete, and drag and drop in the same way you always do. Press Enter to add a new line.
In order to write a symbol, click on its icon and it will appear in the current location of the cursor. For instance, in order to write , click on the “Operators” tab, then on , then on the “Greek” tab, and finally on the icon.
In order to change some text to bold face or italics, select it and click on the B and I icons.
