Opera 12.50 snapshot 1577: 内核升级、支持键盘文本选择

这次 Opera 12.50 snapshot 内核继续升级，另外加入了使用键盘选择文本的新特性。还有若干 bug 修复。

内核

• 支持对携带 ICC Profiles 的图片进行颜色管理
• 支持全屏/Fullscreen API（很快将支持最新版本的 全屏 API 规格）
• 对 SPDY 协议的支持总算从实验室版本毕业，并入主干版本。今天这个版本捆绑了一个扩展，如果当前网页支持并正在使用 SPDY（例如 Twitter），该扩展会告知用户
• 扩展增加 上下文菜单/Context Menu API，允许扩展向网页右键菜单添加项目（API 文档）
• 支持对 @media 代码块使用嵌套形式 (nested @media blocks)。这是实现 CSS 3 条件规则的第一步
• 支持有序列表的 HTML5 reversed 属性

这些新特性的详情、例子和代码示例请见 Opera Developer News。

使用键盘选择文本

这个版本增加了使用键盘选择文本的功能。这个功能的开关，默认是 F7 键。按 F7就会出现一个光标，然后可以使用箭头键移动光标（并配合 shift 选择文本）。

Mac 上对按键事件的处理

Mac 平台上长期存在的按键事件处理方式的问题得到了修复。现在 event.ctrlKey 和 event.metaKey(Command) 不再互换，这是最大的调整，有可能引发网站兼容问题。现在 ctrlKey 由物理按键 ctrl 触发。其他事件应该和 DOM Level 3 按键事件处理方式一致。

已知问题

• 自动更新后，快速拨号只显示空白
• Linux/FreeBSD 平台上所有插件都引发崩溃
