Chrome’s keyboard scrolling to get better, thanks to Microsoft

Chrome on Windows PC

Microsoft has caused a bit stir with its new Edge browser based
on Google’s open-source Chromium and Blink rendering engine
project. The Chromium underpinnings allow Microsoft Edge to
access extensions, a couple of cool features, and the updated
version is much more efficient.

While Chrome runs without any noticeable lag when scrolling,
Microsoft believes there’s still room for improvements.
Microsoft has already ported Edge-style scrolling to Chromium
and the Washington tech giant is now working on improved
keyboard-based scrolling experience.

Microsoft is adding percent-based scrolling support for the
keyboard, so each keyboard-initiated scroll will be interpreted
as a percentage of the size of the viewport and you’ll notice
minor improvements when scrolling with the arrow keys.

“Keyboard arrow scrolling and scrollbar button scrolling should
also scroll a percentage of the scrollable area when percent
based scrolling is enabled,” Microsoft explains.

“This CL adds plumbing from the base::Feature to blink, and
uses 1/8th as the percentage to use for directional scrolls via
keyboard arrows or scrollbar buttons. Adds a test suite that
runs scrollbar tests in percentage mode. Keyboard is currently
handled on the main thread so we just use the runtimeFlag
toggling via javascript and eventSender,” wrote Daniel Libby, a
member of Microsoft Edge team.

It’s possible that Microsoft has already implemented keyboard
scrolling improvements in its Edge browser and the new Chromium
code will also enable a similar experience in Chrome.
