Zoomer

The Zoomer options allow you to customize the magnifier's level, position, and size, as well as to hide the system pointer.

Factor de escala

Scale factor can be used to set the magnification level from 1.0x to 16.0x (fractional values are supported).

Posicións

Position can be used to specify the placement of the magnifier on your screen. The available positions are: Full Screen, Left Half, Right Half, Top Half, Bottom Half, and Custom.

Valor predeterminado: Pantalla completa

Specifying the Bounds of a "Custom" Zoomer

Choosing a Position of Custom causes four spin buttons to become available: Top, Left, Right , and Bottom.

These spin buttons allow you to define the location of each edge of the zoom window. Units are in pixels.

Agochar o punteiro do rato

The Hide system pointer checkbox will hide the unmagnified pointer, leaving just the magnified one visible.

Tracking and Alignment

Punteiro do rato

The Mouse Pointer combo box allows you to select your tracking and alignment from the following options:

Centered: Keeps the mouse pointer at the center of the screen whenever possible.

Proportional: Positions the mouse pointer in the zoom window relative to its actual, unmagnified position. For instance, if the mouse pointer is 25% away from the left edge of the desktop, Orca positions the magnified mouse pointer 25% from the left edge of the zoom window.

Push: Moves the zoomer window the least amount necessary to keep the mouse pointer on the screen.

None: Moving the mouse pointer has no impact on what the zoomer window displays.

Valor predeterminado: Centrado

Pointer follows zoomer

The Pointer follows zoomer checkbox allows you to customize what should occur if the mouse pointer is not on the screen when you initially move the mouse. With this option enabled, if the mouse pointer is not on the screen when you initially move the mouse, it will be moved into the zoomer so that you can continue to see what you were working on. If your preferred mouse tracking mode is centered, the pointer will be moved to the center; otherwise it will be moved to the item with focus.

Valor por omisión: marcado

Elemento de control e de menú

These options control additional behavior of the magnifier.

Centered: When navigating via keyboard, keep the focused dialog box control or menu item at the center of the screen whenever possible.

Push: When navigating via keyboard, move the zoomer window the least amount necessary to display the focused dialog box control or menu item.

None: Using the keyboard to navigate among dialog box controls and menu items will have no impact on what the zoomer window displays.

Default value: Push

O punteiro segue o foco

Pointer follows focus: If this option is enabled, the mouse pointer will follow you as you arrow through menu items and move among controls in dialog boxes.

Valor predeterminado: non marcado

Cursor de texto

Estas opcións controlan como se comporta o cursor de texto

Centered: As the text cursor moves, keep it at the center of the screen whenever possible.

Push: As the text cursor moves, move the zoomer window the least amount necessary to display it.

None: Moving the text cursor will have no impact on what the zoomer window displays.

Default value: Push

Edge margin

The Edge margin is how close the caret should be allowed to get to the edge of the screen before it's time to "push" the zoomer window. The margin can range from 0 to 50%, with 50% being the equivalent of choosing centering.

This option is only available if "Push" is your text cursor tracking mode.
