Postbox 2 includes a bunch of keyboard shortcuts to make it easier to navigate through the interface and quickly triage messages:

• We've simplified the tab functions within the three pane interface, and have made it much more obvious as to what is currently being selected.
• You can now use the left and right arrow keys to move between the various panes in the main window:
  • When a message is selected, you can use the right arrow to open that message in a new tab, and the left arrow will move to the pane to the left.
  • When a conversation is selected, the right arrow will expand the conversation, and the left arrow will collapse it and then move to the pane to the left.
• Some of the new short cuts in Postbox 2 include access to Quick Folder Switch, Quick Move, Quick Reply, and the ability to open and close the Inspector Pane, Folder Pane, and Focus Panes to customize your view.
