LessonUp can display all punctuation marks, regardless of the language. The method for inputting a punctuation mark greatly depends on your operating system. Most Windows users are likely familiar with the ALT+[number] key combination. In fact, some of these combinations are ingrained in collective memory. A useful website to find all key combinations is "How to Type."

Apple users often find it easier. Apart from finding punctuation marks and accents using ALT+[letter], in MacOS, holding down the desired letter displays various accents for that letter. Of course, all punctuation marks and accents can also be copied from an internet page or a document, but this is often more cumbersome.

A square meter is represented as m² and not as m2. This is the indication of a second class in secondary education. In LessonUp, in slides, you can find the buttons for sub- and superscript by selecting the text and then clicking on the button with the capital letter A.

In the interactive components, you first need to use a Text component (via the + Component button) to add sub- and superscript in the question. We've explained how to do this here. Additionally, you can add sub- or superscript to answer options in a quiz. We'll further explain the possibilities of answer options here.

The best way to add fractions or formulas is through the formula editor in LessonUp. You can access it via the + Component button. LessonUp's formula editor utilizes KaTeX, which was co-developed by the Khan Academy.

You can make your lesson more engaging with emojis. These emojis can often be easily sourced from the internet, but you can also insert them using the keyboard. Apple users can access emojis by simultaneously pressing the CTRL+CMD+Space keys. Then, you can search for and insert the desired emoji into your lesson. In Windows, you can do this by simultaneously pressing the Windows key (with the Windows logo) and the key with a dot.
