When the user splits a view, little wedges pointing up, down, left or right are displayed at the upper left-hand corner of the panes. These are very handy in expanding the current pane and then restoring it to its previous configuration. I would like to create keyboard shortcuts for these useful functions, but I haven't been able to identify the commands by looking in the shortcuts list or in the API list. Can anyone tell me what these commands are called, and if they can be activated by a user shortcut?
