The Selection tool is designed to select multiple events across tracks by drawing selection boxes around the
events you want to include. The Selection tool can draw three types of selection boxes:
Type Description
Free Selection The default behavior of the tool:
n Click to select individual events (hold Shift or Ctrl to select
multiple events).
n Drag to draw a rectangular region that begins where you start
drawing and ends where you release the mouse button. All of
the events that are inside the region will be selected. This
method is good for selecting a group of events that are close
together.
Vertical Can be used to easily select all events that occur within a time range.
The vertical selection box automatically selects all of the tracks
between your first mouse click and where you draw the selection box;
even tracks that are not visible at the current magnification are
selected.
Horizontal Can be used to easily select all events on a single or multiple adjacent
tracks. The horizontal selection box automatically selects all events
on a track that is touched by the selection box; even events that are
not visible at the current magnification are selected.
To change the type of selection box you are using, right-click the mouse while holding down the left mouse
button. Clicking the right mouse button will toggle through the three types of selection boxes.
