WordNav NVDA add-on improves built-in navigation by word, as well as adds extra word navigation commands with different definition for the word. It also provides word selection commands.

A maioria dos editores de texto suporta os comandos Control+Seta para a esquerda/Seta para a direita para navegar nas palavras. No entanto, a definição da palavra muda de um programa para outro. Isto é especialmente verdade nos editores de texto modernos baseados na Web, como o Monaco. O NVDA deve conhecer a definição da palavra num determinado programa para poder dizer as palavras correctamente. Se o NVDA não souber a definição exacta, então as palavras serão ignoradas ou pronunciadas várias vezes. Além disso, alguns editores de texto baseados na Web posicionam o cursor no fim da palavra, em vez de no início, tornando a edição muito mais difícil para os utilizadores com deficiência visual. Para combater este problema, criei comandos de navegação de palavras melhorados, que utilizam a definição de palavras do Notepad++ e não dependem da definição de palavras do programa, mas analisam as linhas em palavras do lado do NVDA. O gesto Control+Seta para a esquerda/Seta para a direita nem sequer é enviado para o programa, garantindo assim a consistência do discurso.

Word navigation and word definitions

Currently WordNav supports five definitions of the word, assigned to different gestures:

• Controlo esquerdo+Setas: Definição do Notepad++, que trata os caracteres alfanuméricos como palavras, e os sinais de pontuação adjacentes também são tratados como palavras. Esta deve ser a definição de palavra mais conveniente para a maioria dos utilizadores.
• Controlo direito+Setas: A definição de palavra fina divide camelCaseIdentifiers e underscore_separated_identifiers em partes separadas, permitindo assim que o cursor vá para identificadores longos.
• LeftControl+Windows+Arros: Bulky word definition treats almost all punctuation symbols adjacent to text as part of a single word, therefore it would treat paths like C:\directory\subdirectory\file.txt as a single word.
• Controlo direito+Windows+Setas: Definição multipalavra, que agrupa várias palavras. A quantidade de palavras é configurável.
• Unassigned: custom regular expression word definition: allows user to define a custom regular expression for word boundaries.

Os atalhos podem ser personalizados no painel de configurações do WordNav.

Word selection

Word selection is supported starting with WordNav v2.0. Just add shift modifier to any word navigation gestures to select words. There is also one extra gesture for word selection:

• control+shift+numpad1 and control+windows+shift+numpad1 select word to the right similar to their rightArrow counterparts, but they also include trailing spaces into selection.

Please note, however, that currently used accessibility APIs have multiple issues related to word selection. Please get yourself familiar with the following list of issues and workarounds:

• UIA applications (e.g. Notepad, Visual Studio, Microsoft Word) don't support setting caret at the beginning of selection. In those applications caret location is stored on WordNav side. As an adverse side effect, word navigation commands might not play well with line and paragraph selection commands (shift+up/downArrow, control+shift+up/downArrow) and results might be unpredictable. For convenience, character selection commands (shift+left/rightArrow) have been updated in WordNav for UIA applications and should work well.
• Basic single line Windows edit controls also don't allow to set the caret in front of selection, so the previous point also applies to them. This affects all single line edit boxes within NVDA.
• IAccessible2 doesn't provide a way to set selection spanning across multiple paragraphs. There is no known workaround for this issue. This affects rich multiline edit boxes in Chrome and Firefox, such as compose email text area in GMail and compose email window in Thunderbird.
• In notepad++ selection update messages come unreasonably slow. As a workaround, WordNav announces selection on NVDA side for word selection commands and silences late notifications for the following 0.5 seconds. As a result, if you press word selection command followed by another (e.g. character) selection command in quick succession, you might miss selection notification for the latter one if it came within 0.5 seconds from the last word selection command.
• In multiline edit boxes supporting TOM interface NVDA incorrectly identifies cursor location when selection is present. This has been fixed in nvaccess/nvda#16455, which is scheduled to be included in NVDA v2024.2 release. Before that release word selection commands won't work correctly in TOM edit boxes, such as NVDA log viewer.

Notas

• Se pretender utilizar a funcionalidade de ambientes de trabalho virtuais do Windows 10, lembre-se de desactivar os atalhos de teclado Control+Windows+Setas no painel de configurações do WordNav ou no diálogo definir comandos, no NVDA.
• Compatibility with VSCode requires NVDA add-on IndentNav v2.0 or later to be installed. Additionally, VSCode extension Accessibility for NVDA IndentNav must be installed in VSCode.
