Selecting multiple segments
Several road segments may be selected at once in order to change properties of several segments at one time. There are several ways to select multiple segments.
One way is to select the first segment, then use ctrl+click (MAC users:⌘ Command+click) to select additional segments.
A second way is to use multi-select mode. Use the shortcut key m to enter multi-select mode. Click each segment -- all will remain selected. To exit multi-select mode, use ctrl+click (or ⌘ Command+click).
To select segments between two segments, first select a segment, then use alt+click to select a second segment. The editor will select the segments in between the first segment and the second segment based mostly on street name but also on simple straight lines.
To select all segments within a box use ctrl+⇧ Shift+click (MAC users:⌘ Command+⇧ Shift+click) and then drag the cursor while holding the mouse button to form a box. When the mouse button is released, all the segments in the box are selected.
Segments having the same properties can be selected using the "Select entire street" function. To use this function, select a segment and then press the "Select entire street" button in the left pane. The shortcut key ctrl+a can be used rather than the button.
