  27 ;; This file contains the code to interact with Richard Moreland's iPhone
  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.

 102 SECURITY CONSIDERATIONS:
 103
 104 Note that, when Org runs the encryption commands, the password could
 105 be visible briefly on your system with the `ps' command.  So this method is
 106 only intended to keep the files secure on the server, not on your own machine.
 107
 108 Also, if you set this variable in an init file (.emacs or .emacs.d/init.el
 109 or custom.el...) and if that file is stored in a way so that other can read
 110 it, this also limits the security of this approach.  You can also leave
 111 this variable empty - Org will then ask for the password once per Emacs
 112 session."

 954 These shortcuts are meant for fast and easy typing on the limited

 956 currently implemented.
 957
 958 The entry is expected to contain an inactive time stamp indicating when
 959 the entry was created.  When setting dates and
 960 times (for example for deadlines), the time strings are interpreted
 961 relative to that creation date.
 962 Abbreviations are expected to take up entire lines, just because it is so
 963 easy to type RET on a mobile device.  Abbreviations start with one or two
 964 letters, followed immediately by a dot and then additional information.
 965 Generally the entire shortcut line is removed after action have been taken.
 966 Time stamps will be constructed using `org-read-date'.  So for example a
 967 line \"dd. 2tue\" will set a deadline on the second Tuesday after the
 968 creation date.
 969
 970 Here are the shortcuts currently implemented:
 971
 972 dd. string             set deadline
 973 ss. string             set scheduling
 974 tt. string             set time tamp, here.
 975 ti. string             set inactive time
 976
 977 tg. tag1 tag2 tag3     set all these tags, change case where necessary
 978 td. kwd                set this todo keyword, change case where necessary
