When creating or editing questions that require text responses -  you can select different text editor types, depending on your requirements.

For short text questions - eg Title, Name, there are two options, with the first also allowing for symbols. 

With long text questions there are further options, with an increasing list of permissible text types.

Text boxes on forms will appear as below for each option. Note that the bottom right corner is marked with diagonal stripes. This denotes that you can extend and contract the size of the box by clicking and dragging at that point.

Plain Text

 Type 1, which is the same as 'Basic formatting...'

 Type 2

Type 3

Type 4

Although there is no image icon in Type 4, the text box allows for images. When answering long text questions, usually for abstracts, we always recommend submitters copy and paste from WORD or similar, for formatting consistency.
