25;;; Commentary:
26;;
27;; This file contains the code to interact with Richard Moreland's iPhone
afe98dfa
CD		 28;; application MobileOrg, as well as with the Android version by Matthew Jones.
29;; This code is documented in Appendix B of the Org-mode manual. The code is
30;; not specific for the iPhone and Android - any external
31;; viewer/flagging/editing application that uses the same conventions could
32;; be used.

105SECURITY CONSIDERATIONS:
106
86fbb8ca 107Note that, when Org runs the encryption commands, the password could

109only intended to keep the files secure on the server, not on your own machine.
110
111Also, if you set this variable in an init file (.emacs or .emacs.d/init.el
112or custom.el...) and if that file is stored in a way so that other can read
113it, this also limits the security of this approach. You can also leave
114this variable empty - Org will then ask for the password once per Emacs
115session."

961The entry is expected to contain an inactive time stamp indicating when
962the entry was created. When setting dates and
963times (for example for deadlines), the time strings are interpreted
964relative to that creation date.
8bfe682a 965Abbreviations are expected to take up entire lines, just because it is so
8d642074
CD		 966easy to type RET on a mobile device. Abbreviations start with one or two
967letters, followed immediately by a dot and then additional information.
968Generally the entire shortcut line is removed after action have been taken.
969Time stamps will be constructed using `org-read-date'. So for example a
970line \"dd. 2tue\" will set a deadline on the second Tuesday after the
971creation date.
972
973Here are the shortcuts currently implemented:
974
975dd. string set deadline
976ss. string set scheduling
977tt. string set time tamp, here.
978ti. string set inactive time
979
980tg. tag1 tag2 tag3 set all these tags, change case where necessary
981td. kwd set this todo keyword, change case where necessary
