# Specifying Custom Forecast Modifiers

In addition to the commonly used forecasting models found on the Model context menu, Forecast Pro supports a broad range of custom modeling modifiers. These modifiers accommodate a wide range of modeling options including confidence limit percentiles, safety stock lead times and power transformations.

Custom modifiers are entered using the **Custom Modifier** option on the Navigator’s context menu. Consult the *Forecast Pro Reference Manual* for documentation of all available modifiers.

Experiment with the various modeling options until you are comfortable with their operation. When you are finished, exit the program. This concludes the *Customizing Forecasts* tutorial.
