The Palette Directories (IPCBE) mask settings determine which fixed function kinds are recorded into palettes for that directory if the command line kind mask is blank at the time of recording (no kinds selected). To change which kinds are included in the directory's mask open the configuration window for that directory, navigating to the mask tab, and enable/disable the individual function kinds in the menu.
A directory mask legend is shown at the top of each directory window and indicates which kinds will be recorded into palettes for that directory if the kind mask is blank at the time of recording.
