Once a selection is made, you can save it with the Push Selection command (in menu Edit / Selection). The highlighting is not changed, but it is saved on a stack. To restore this selection at a later time, use the Pop Selection command.

There are some selection preferences that can be set with "Selection" preferences (in menu File / Preferences..., "General" section, "Selection" tab). "Easy selection" controls whether objects can be selected with simple clicks, or whether they require extra effort to select. You can request that all cell instances be hard to select and that all annotation text be hard to select. See the (next section) for more on this.

The "Dragging must enclose entire object" requests that area-selection completely enclose an object in order to select it. The default is that any object touching the area is selected.

To prevent accidental moving of an object after selecting it, object movement is disabled for a short time after the selection click. This delay can be controlled.

When the cursor roams over a circuit, it shows a "preview" of what will be selected by the next click. The advance preview is shown in a different color than the actual highlighting (initially blue, but this can be changed with the see "Color" Preferences). This feature is called "mouse-over highlighting". If you do not want to see this preview, uncheck "Enable Mouse-over highlighting".
