Writer: If you click the icon with a short-click while no text is selected, then the mouse pointer changes its appearance and is displayed as a paint can. Use this paint can symbol with the mouse key pressed to drag across a text area. This text area takes the selected colour. The function remains active for as long as the icon is pressed, or until you click without dragging, or until you press the Escape key.
Writer：如果在没有选择文字的情况下，快速单击此图标，鼠标指针的外观将修改为油漆桶形状。按住鼠标键将油漆桶符号拖过某个文字区域。这时，该文字区域将修改为选定的颜色。只要图标显示为按下状态，此功能就始终有效。直到单击鼠标而未同时拖动，或按 Escape 键，此功能才会关闭。
