https://harmattan-bugs.nokia.com/show_bug.cgi?id=1081


OPERATING SYSTEM:
Meego Harmattan

PRECONDITIONS
Built in browser

STEPS LEADING TO THE PROBLEM:
1. Open default browser (web icon)
2. Tap the right edge of the screen (be careful not to start a swipe)
3.

EXPECTED OUTCOME:
Try it on PR1.1 to see the expected behavior.
Short description: When you tap on the top or bottom of the right edge of the screen the page scrolls up or down. If you tap at the middle of the right edge the page toggles zoom in and out to overview/reading magnification.

ACTUAL OUTCOME:
Nothing happens. Sometimes the nearest link is followed

FREQUENCY OF OCCURRENCE:
Always

NOTE:
I am not sure this was an intended behavior in PR1.1 but it was really useful. Now I find myself always clicking on unwanted links trying to zoom in and out.

Pinch zoom is difficult with one hand, and double-tap does not always produce a sensible reading magnification (especially on wide blocks of text, or blocks of text with right floats in them). Middle tapping the right edge solved that problem brilliantly. Also scrolling with tapping was faster than swiping for longer pages.
