Option (Mac) / Alt (Win) -click on a color swatch to delete it in the Swatches panel. Note: this shortcut also works on the Styles panel and in the Preset Manager (Edit > Preset Manager). The advantage to using the Preset Manager is that you can click on one swatch, then Shift-click another to select multiple contiguous swatches (or Styles, Brushes etc.) and delete them all at once. In addition, the Preset Manager enables drag-reordering items which is not possible in the individual panels.
