Summary:
1. "Previous Slot" action moves the selection box to the beginning of the time slot not the end.
It looked to me as an obvious mistake.
2. Both "previous slot" and "next slot" move the selection box in intervals defined in calendar_timeslots
option instead of one hour. I.e. it will be one hour, 30 minutes, 20 minutes, 15 minutes or 10 minutes,
depending what's configured in Preferences > Calendar > Time slots per hour.
