FingerRead — 滚轮指读 作者： Sam Huang

FingerRead brings finger tracking to the browser: select a passage, turn the scroll wheel, and a highlight moves through the text. Scroll quickly and it skips ahead; scroll slowly and it advances one character at a time. It pauses briefly at sentence ends so you never lose your place.

Unlike text-to-speech, there is no preset reading speed — your hand sets the pace.

Highlights
· Select and scroll — nothing to configure
· Character or word stepping (Chinese word segmentation; word mode needs a membership, available during the trial)
· Works on real pages: shadow DOM, nested scroll containers, dynamically loaded content, contenteditable editors
· Drops the session when the text changes underneath you, so no stale highlight is left behind
· Privacy first: highlighting happens inside the page. The text you read is never uploaded; the server only stores your email and membership state
· Membership is tied to your email account: up to 3 authorized devices per account, and you can revoke any device from the options page at any time
· Install the Firefox build right here; Chrome and Edge builds are in store review and will be announced once live

FingerRead 把「指读」搬到浏览器里：选中一段文字，滚动滚轮，高亮就沿着文字推进。
滑得快，它跳得远；滑得慢，它一个字一个字地走。遇到句尾会短暂停留半拍，让你跟得上。

不像语音朗读，无需预设语速——节奏完全由你的手决定。
