Pick several items, copy and undo
Pick several items with Shift, then move, duplicate, copy, delete or restyle them together; copy and paste items; and undo or redo changes.
Transcript
To work on several items at once, hold shift and click each one, or hold shift and drag a box around them. A bar at the bottom shows how many you've picked. Move them to another layer or phase, duplicate them into another phase, copy them, or delete them. Picked several measurements? Edit style changes the settings you touch on all of them, and leaves the rest as they are.
Control C copies them, and control V pastes them where the mouse is. Control D duplicates the open item. Made a mistake? Control Z undoes it, and control shift Z puts it back.
