3.4 Mouse Actions

XTrackCAD uses the left and right mouse buttons when manipulating tracks and other objects on the layout. Their meaning depends on the particular command:

Select Command

The Select command actions are affected by the mode selected in Options->Command->Select. Note - Objects in a Module Layer are selected and deselected as a group.

Left-Click
Single Item Mode -> Selects one object at a time, deselects other objects. Add Item Mode -> Adds unselected objects, deselects if the object is already selected. If the click is on an area without objects and SelectZero is set, all objects are deselected.
Shift-Left-Click
Selects all connected tracks from the one clicked up to the next selected item in each direction.
Ctrl+Left-Click
Single Item Mode -> Adds an object to the selection, deselects if the object is already selected. Add Item Mode -> Selects just this item and deselects other objects. If the click is on an area without objects and SelectZero is set, all objects are deselected.
Double-Left-Click
Opens Modify for Cornu and Draw Objects other than Text, Activates Link and Document Notes, otherwise opens Describe.
Left+Drag
Single Item Mode -> Selects all objects in an rubber-banded area and deselects all others. Add Item Mode -> Adds items in the rubber-banded area.
Shift+Left-Drag
Moves selected objects if in a selected area, if off selected objects, like Left-Drag.
Ctrl+Left-Drag
Rotates selected objects if in a selected area, if off selected objects, like Left-Drag.
Right-Click
Displays a pop-up menu of context commands (in Select, Move, Modify and Rotate commands). If some track is selected, the menu has operations to perform on it, if not, it will have a command context menu.
Shift+Right-Click
Displays a pop-up menu of commands. Displays the other context menu than Right-Click.
Right+Drag
Deselects all objects in an rubber-banded area from the current set.
Rotate Wheel
Zooms drawing area in and out. Modern computers with Trackpads often map this guesture to two-finger drag.

When Moving and Rotating ( Placing Turnouts and Structures, Moving the Print and Snap Grids, ... ):

(Shift+Left+Drag)
Moves the objects or grid.
(Ctrl+Left+Drag)
Rotates the objects or grid about the pivot point, which is the point you started the drag operation.

Some other commands use the Shift or Ctrl key to modify the meaning of button presses.
