Adding, Editing and Formatting Text

    In addition to atom labels, it is also possible to add blocks of text in a text box. These text boxes are resizable, outlined by a border, have a background, but are not fitted to the text automatically.

    Create a Text Box

    1. Click on the Text tool on the Tools toolbar or use the Text item of the Insert menu.
    2. Click and hold the left button, move the mouse, and release the button.
    3. To place the text box, click again.
    4. Type the text.

    The shape textbox is changeable or resizable by dragging one of its points or the selection.


    When the text box is selected and copy-pasted, the format (text style, size, color, alignment, super, and subscript, and so on) is preserved. When only the text is selected and copy-pasted, it is handled as text, that is, it can be recognized as a name or chemical file when pasted.

    Editing and Formatting Text

    The default formatting options can be set in the Preferences menu. To apply different formatting to the text, use the Text Edit toolbar.

    Text editing options

    The following functions are available on the toolbar:

    • Font type
    • Font size
    • Bold
