| 説明 | I was thrilled to discover that elevators in China had implemented something I'd always wanted to see: an undo feature.Some work like this, where pressing an already lit button causes it to flash, and a second press causes it to turn off. Others require a double click to get into the flash mode. In both cases, the idea is to support an "undo" mode while also allowing for someone who accidentally just presses a button that was already pressed. |
