10.3.4 Timeline for a single file
---------------------------------
The timeline summarizes all time-stamped items from a single Org mode
file in a _time-sorted view_. The main purpose of this command is to
give an overview over events in a project.
‘C-c a L (org-timeline)’
Show a time-sorted view of the Org file, with all time-stamped
items. When called with a ‘C-u’ prefix, all unfinished TODO
entries (scheduled or not) are also listed under the current date.
The commands available in the timeline buffer are listed in 
Agenda
commands.
