Visibility - Palettes
All of the palette groups in the drawing are listed in the middle panel. You should identify a palette group and then all of the palettes in that group will be displayed in the right-hand panel. Highlight the palettes you want to be made visible.
You can click on a palette to highlight only it, control-click to toggle it while leaving other items unchanged and shift-click to highlight a range. Right-clicking also allows you to: Select All, Select None, Toggle Selection, Select By Regular Expression.
