Mouse

Mouse usage in screen zooming and object pointing.

Zoom method

Zoom method is selected from the Zoom-menu or popup-menu and it determines the mouse usage in screen zooming.

Box

Keep the left mouse button pressed and form the box by dragging to any direction. When you release the button, the picture is zoomed to box. If you want to cancel the function, take the mouse back to the start point and the box disappears.

Pan

Move the mouse to the point you want to pan, keep the mouse button pressed and drag to the required position.

You can swap between these two modes by holding down the Ctrl-key while dragging the mouse with left ear pressed. This is not permanent change. Original mode will be used next time.

You can use also mouse center button (wheel) for Pan-function.

Left button

Clicking with the left button without moving the mouse works as point selection or coordinate pointing. Exact behavior depends on the current search mode.

Wheel (center button)

Mouse wheel rotation can be used for screen zooming and, with most mouses, for panning by pressing it. Rotating the wheel forward zooms nearer to the mouse position and rotating backward zooms away from it.

Ctrl- and Shift-keys can be used for slower or faster zooming. Keeping the Ctrl-key pressed the wheel zooms slower and with the Shift-key faster.

Double click zooms all to screen.

Right button

Right mouse button opens the popup-menu.

Continuous coordinate

Moving mouse with both the left button and the Shift-key pressed sends continuous mouse position to all open dialogs.

Distance measurement

With the Ctrl-Alt keys the zoom mode is skipped and the mouse is used for distance measurement. When the left mouse button is pressed while moving the mouse, line with distance and direction values is draw on the screen. Line disappears, when the mouse button is released.

In cross section and profile windows X and Y distance components are displayed separately and the direction is replaced by the slope relation value.

3D-rotation

In the 3D-view mouse with the Alt-key can be used to rotate view. Horizontal mouse move changes the horizontal angle and vertical move changes the vertical angle.

Note, that the vertical angle change is slower near horizontal plane and faster when viewing from higher.
