GNOME Bugzilla – Bug 775133
SPACE and BACKSPACE no longer scroll message preview
Last modified: 2016-11-26 13:16:05 UTC
When the message list has focus, SPACE and BACKSPACE are supposed to scroll the message preview, according to the docs: Navigating in a message To read mail with the keyboard, you can press the Spacebar to page down and press Backspace to page up while reading an email. Ensure that you use the keys when the message list is focused. This no longer works in Evolution 3.22. Tested on Fedora 25 and Debian Unstable.
