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

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

"Parse the entry at point for shortcuts and expand them.
These shortcuts are meant for fast and easy typing on the limited
keyboards of a mobile device. Below we show a list of the shortcuts
currently implemented.
The entry is expected to contain an inactive time stamp indicating when
the entry was created. When setting dates and
times (for example for deadlines), the time strings are interpreted
relative to that creation date.
Abbreviations are expected to take up entire lines, just because it is so
easy to type RET on a mobile device. Abbreviations start with one or two
letters, followed immediately by a dot and then additional information.
Generally the entire shortcut line is removed after action have been taken.
Time stamps will be constructed using `org-read-date'. So for example a
line \"dd. 2tue\" will set a deadline on the second Tuesday after the
creation date.
Here are the shortcuts currently implemented:
dd. string set deadline
ss. string set scheduling
tt. string set time tamp, here.
ti. string set inactive time
tg. tag1 tag2 tag3 set all these tags, change case where necessary
td. kwd set this todo keyword, change case where necessary

auto-correction feature. Needs a bit more thinking. So this function
