7.2 Special Properties

Special properties provide an alternative access method to Org mode features, like the TODO state or the priority of an entry, discussed in the previous chapters. This interface exists so that you can include these states in a column view (see Column View), or to use them in queries. The following property names are special and should not be used as keys in the properties drawer:

ALLTAGSAll tags, including inherited ones.
BLOCKEDt if task is currently blocked by children or siblings.
CATEGORYThe category of an entry.
CLOCKSUMThe sum of CLOCK intervals in the subtree. org-clock-sum
must be run first to compute the values in the current buffer.
CLOCKSUM_TThe sum of CLOCK intervals in the subtree for today.
org-clock-sum-today must be run first to compute the
values in the current buffer.
CLOSEDWhen was this entry closed?
DEADLINEThe deadline timestamp.
FILEThe filename the entry is located in.
ITEMThe headline of the entry.
PRIORITYThe priority of the entry, a string with a single letter.
SCHEDULEDThe scheduling timestamp.
TAGSThe tags defined directly in the headline.
TIMESTAMPThe first keyword-less timestamp in the entry.
TIMESTAMP_IAThe first inactive timestamp in the entry.
TODOThe TODO keyword of the entry.
