End-user available texts allow to make use of special strings which allow to deal as placeholders and symbols, adjustments due to inflection, or change the formatting.

General
Special Strings are always enclosed in curly brackets. Depending on the content within these curly brackets a certain command is triggered. These commands can be grouped as follows:
- Replacement for symbols such as a train symbol, a bus symbol, or the "X" symbol at the top of a window to close it,
- Change formatting such as making text colour look green/red/..., or changing the font size,
- Placeholders such as another string, a value for a cargo that is waiting at a station, or a vehicle's number,
- Inflection such as adjustments to other words to allow context-aware translation.
See below for a complete list of commands currently available:
