conversation-list-view: add single key shortcut for selection
This adds a single key shortcut for toggling the selection state of conversations in the conversation list.
When single key shortcuts are enabled, pressing x
in the conversation list
will enter selection mode. While in selection mode, the j
and k
shortcuts
can be used to move through the list pressing x
to toggle whether the convo is
included in the selection. If all conversations are unselected, then selection
mode is automatically ended.
