WIRIS Editor is a WYSIWYG formula editor designed to streamline the process of writing mathematical formulae. It is a powerful tool that allows composing any math expression with high graphics quality, while remaining simple and easy to learn.

There are two ways you can open WIRIS editor: 

  • If you want to write a new formula, click on the icon in the editor toolbar.
  • If you want to modify an existing formula, select it and click on , or just double click on it.


After writing or modifying the formula, click on OK if you want to insert the formula as it is shown, or Cancel if you want to exit without saving changes.

Formulae are treated as any other kind of object:

  • You can select formulae by either clicking on them or by moving the cursor over them while holding the SHIFT key.
  • You can erase formulae by selecting them and pressing delete, or by moving the cursor after (before) them and pressing the delete (supr) key. If you delete a formula accidentally, you can recover it by clicking on the undo icon , or pressing CTRL-Z.
  • You can cut, copy and paste formulae in the usual way, by pressing CTRL-X, CTRL-C and CTRL-V; this is particularly useful when you have to write several formulae which are very similar. You can apply all of those edition operations to a single formula or to combinations of formulae and text, and you can paste to other WIRIS windows.
  • You can also drag&drop a formula with the mouse.
