The following changes have been rolled out to production:
- The keyboard shortcut to select all has changed: it is now "* a", which means press the star key (normally shift-8), then after that press the "a" key within 1 second. You can deselect all using "* n" (star followed by the "n" key). The previous shortcut of just "a" on its own conflicted with the shortcut for reply to all when the reading pane is active, and it was also too easy to accidentally select all before hitting another key which could then perform an action on all those messages.
