Engee documentation

Abstracts

Abstracts are formatted using text markup, the usage of which is described in the article Text markup in Engee.

Annotations annotation 1 1 are areas in workspace Engee where you can add text and format it, add lines of code, images, and more using markup languages. For example:

annotation example 1 en

For example, the annotations use the syntax of the markup language Markdown with the ability to extend the functionality using HTML and LaTeX.

To add annotations, left-click on an empty area of the Engee workspace. This will open a context menu with an Add Annotation button annotation 1 1:

annotation 1 en

Annotations are a level below any Engee workspace elements, eliminating their unwanted overlap with the Engee model or interface tools.

Interface

Adding an annotation opens the available interface

annotation 2

  1. Bold annotation 3

  2. Italics annotation 4

  3. Underlined annotation 1 x

  4. Strikethrough annotation 5

  5. Monospaced annotation 2 x

  6. Highlighted annotation 3 x

As well as other actions annotation 4 x, which include a basic set of auxiliary templates for text markup:

annotation 5 x

Templates help you use all the basic functionality of annotations without diving into the subtleties of markup language syntax!

Inserting images

The following syntax is used to insert images:

![]()

You can specify alternative text in square brackets [], and in round brackets () you can specify a link to an image on the Internet. Annotations in Engee do not support local paths to images lying in file browser file browser 7.

Formulas

The KaTeX library is used to write formulas in annotations. To display a formula correctly, enclose single-line expressions in $…​$ and multi-line expressions in $$…​$$$. This is necessary both for correct rendering and for the work of the visual editor (WYSIWYG), which recognises formulas only by this framing. For example:

Code (KaTeX)

Formula display

 
$x = \frac{-b \pm{b^2 - 4ac}}{2a}$
 

$$
\frac{1}{\sigma{2\pi}}
\exp\left(-\frac{(x - \mu)^2}{2 \sigma^2}\right)
$$

Single-line formulas can also be wrapped in $$…​$$$, in which case they will be centred and displayed enlarged like multi-line expressions:

annotation example 1 x
After Engee switched to KaTeX, old annotations with LaTeX formulas without $ or $$ will not display correctly. Make sure all formulas are wrapped in $ or $$$, and if necessary, remove any extra escape characters (\) that may have been added automatically.

For more information and to implement more complex syntax, see. official KaTeX documentation.

Specifying a language in a code block

To specify a programming language in an annotation code block, the syntax is used to specify the language after a triple backwards apostrophe. For example, to specify the language Python:

```python
print("Hello, world!")
```

Basic Operations

  • To edit an already created annotation, double click on it with the left mouse button.

  • To move an annotation across the canvas, left-click on it.

  • To delete an annotation, left-click on it and use Del or Backspace. The annotation will also be deleted automatically when you delete its content.

Limitations

  • Annotations do not support interactive drag-and-drop (drag-and-drop) of text, images or files from other sources.

  • Annotations do not support copied coordinate planes from chart window graphs icon 1.
