If no copper items are selected, the net of the copper item under the editor cursor will be highlighted. 网络高亮可以通过使用清除网络高亮动作（快捷键 ）或在原理图中的一个空区域使用高亮网络工具来清除。 默认 情况下， 也会清除网络高亮，但如果需要，可以在偏好

bug fixes. Some of the most notable new features include: A Properties Panel in the Schematic, Symbol, and Footprint editors, which lets you quickly view and edit properties of selected objects. This PCB editor, which was introduced in version 7.0. HTTP libraries, which allow connecting KiCad to a networked component database or ERP system via a REST API. The REST endpoint can provide symbol and panel in the Schematic editor, which lets you search for symbols, labels, and schematic text. This mirrors the search panel in the PCB editor, which was added in version 7.0. The Symbol Fields Table has been

If no copper items are selected, the net of the copper item under the editor cursor will be highlighted. Net highlighting can be cleared by using the Clear Net Highlight action default, also clears net highlighting, but this can be disabled if desired in Preferences → PCB Editor → Editing Options. 选择一个或多个网络进行高亮时，左侧工具栏上的切换网络高亮显示操作变为启用(也可通过快捷键 + 访 问)。此操作将打开或关闭高亮，而无需选择要高亮的新网络。
