Keyboard Range Copy by Daniil Stupnikov

Keyboard Range Copy lets you select and copy text from any regular webpage without using the mouse.

Press Command+Shift+X on macOS or Ctrl+Shift+X on Windows and Linux. Yellow keyboard hints appear over visible words. Choose the first endpoint, scroll as far as necessary, and choose the second endpoint. Everything between the two words is copied automatically.

• Copy upward or downward across long pages.
• Copy a single word by choosing the same word twice.
• Scroll with j/k, d/u, Space, or Page Up/Page Down.
• Works alongside Surfingkeys by capturing selection-mode keys separately.
• Clears the temporary text selection after copying.
• Can also be activated from the extension toolbar button.
• Makes no network requests, collects no data, and stores nothing.

The extension only runs after you explicitly activate it. It cannot run on protected Firefox pages, the built-in PDF viewer, or Reader View.
