changed so it keeps the selection range. It just moves it on one day/week
2000-06-21 Damon Chaplin <damon@helixcode.com> * gui/gnome-cal.c (gnome_calendar_direction): changed so it keeps the selection range. It just moves it on one day/week etc. This makes it very handy for the keyboard shortcut code. * gui/calendar-commands.c (calendar_control_activate): fixed bug setting the radio button active. * gui/e-day-view.[hc]: added support for keyboard navigation and selection of the time range. svn path=/trunk/; revision=3665
