In this chapter, we will discuss how to use the different menus and icons in wiris.
On opening the wiris page, a collection of tabs will appear. Examples include Edit, Operations or Analysis. At any time the contents of only one tab are visible. To reveal the contents of a tab, click on the tab name.
Each tab has a set of icons and menus to facilitate building mathematical expressions.
To begin, we will review the content on the tab Operations.
To use the icons on the tab Matrices, click on Matrices.
, and icons will appear that correspond to Matrices
For each of the tabs on the toolbar, a table is presented below to describe the icons and the functions each icon performs, and when applicable a link to a more detailed description is provided. The columns of these tables show us:
Action
A brief explanation of the icon's functionality.
Keyboard
The keystroke combination that can be used as an alternative to the icon in order to speed up the process of building expressions. When such a combination exists, it is included in the icon explanation.
More info
This column provides links that take the user to the quick reference guide section, where a detailed description of the icon’s functionality is provided along with examples of how the icon can be used.
Code
This code is the text that should be entered when the user builds a custom toolbar. For more information, see the chapter on the Toolbar.
General: These icons always appear to the right of the toolbar:

Carries out all the calculations in the active block (set of calculations where the cursor is located). A floating arrow appears close to the active block. It can be used to carry out the calculations, and it disappears when using the keyboard (Ctrl + Enter) to calculate. To make the floating arrow reappear, use the icon at the right of the toolbar. |

Units: SI and other common units. A unit of measurement is created with the icons we can see if we click on the Units tab. In the chapter Units of measurement there are tables provided, relating symbols to units of measurement. If a prefix is selected in the left hand menu, the relevant multiple is created for the selected unit of measurement.
In this folder, there are four groups of units. The first group is made up of the most common units (metre, gram, second ...); the second contains units relating to angles and time, for example:

In the third group are units which are also part of the S.I. system but less commonly used (volt, watt, newton). Finally, in the fourth are icons to create powers of 2 and 3 to facilitate expression building.

Greek: Greek alphabet The icons in this folder permit Greek letters to be used in expression building. In particular the Greek letter pi, which is different from the irrational number, can be created noting that it is shown in black whereas the irrational is blue.
NOTE: If you see no letters in this tab, this means your computer does not have the UNICODE font system installed. This problem does not affect the functionality of the rest of the system.
