Rich text

Rich text formatting introduced in 0.17.0 allows the use of tags within most of the game's textboxes to change the visual formatting of text or to embed interactable images/entities. Predefined text tags are employed for this purpose.

Text modifiers

The color and font of text can be changed

Tags

Tags are useful for sharing blueprints, marking map locations in chat or adding icons to map markers and train stations. Ctrl+alt clicking the map or ground will automatically insert a gps tag and post it into chat.

Shift clicking most things with the console open will insert a tag for that thing into chat.

When used in chat, the tag image will be followed by a text description, except for the img tag. Used elsewhere only the image is shown.
