- This appendix gives an overview on the use of the mouse buttons.

-
- Mouse Button Usage
-
- When you click mouse buttons, the task performed depends on
- three factors:
-
- Ñ the location of the mouse
- Ñ the mouse button that is pressed
- Ñ the current operation mode of ImageTool
-
-
- Normal Button Operation
- Clicking the left mouse button on the canvas when you are using
- the normal mode selects an origin point for drawing operations.
- Clicking twice in rapid succession loads the image specified in the
- Image text field at that location.
-
- The middle mouse button drags a selection box; clicking outside of
- this selection cancels the selection. If instead of clicking outside
- the box you press the middle mouse button inside the box, the cut and
- paste functions are performed on the selection, and you can drag
- the selected area to a new location on the canvas. Alternately,
- holding down CTRL and pressing the middle button with the
- mouse inside the selection box performs the copy and paste
- operations simultaneously. Clicking the right mouse button on the
- canvas undoes the original selection.
-
- Outside of the canvas, pressing the right mouse button activates a
- menu if one is available. The left mouse button can be used to select
- text fields or active control buttons.
-
- Table A.1 summarizes the above overview.
