At work I frequently deal with support issues that my company keeps track of in a web-based bug tracker.
Each issue has an URL that looks like https://mycompany.com/support/SUPPORT-12345, but of course I don't want to spell this out every time I mention a support issue in my Org-mode file. I would like set up Org-mode in such a way that the pattern SUPPORT-(\d+) is treated as a hyperlink to https://mycompany.com/support/SUPPORT-\1.
I would like to be able to place my cursor over the SUPPORT-2345, type C-c C-o, and have Emacs point my browser to https://mycompany.com/support/SUPPORT-2345. Ideally, SUPPORT-2345 would behave no different than a hyperlink.
Can Org-mode be configured in this way? If not, what is the best alternative?
You should be able to do this with org-link-abbrev-alist. For example, see the below for some I use. You can then put [[Support:1234]] in your Org-mode file and have it treated as the expanded link.
(setq org-link-abbrev-alist
'(
("DOI" . "http://dx.doi.org/")
("FreshDesk" . "https://xyz.freshdesk.com/support/tickets/")
("JIRA" . "https://jira.apps.monash.edu/browse/")
("Support" . "https://support.xyz.com/helpdesk/tickets/")
("ISBN" . "http://isbn.nu/")))
I don't know whether Org-mode have this feature, but there is a bug-reference-mode for it.
Here is sample org file:
;; Local Variables:
;; eval: (bug-reference-mode)
;; bug-reference-bug-regexp: "\\(\\(?:\\(?:SUPPORT\\|support\\)-\\)\\([0-9]+\\)\\)"
;; bug-reference-url-format: "https://mycompany.com/support/SUPPORT-%s"
;; End:
* SUPPORT-123
* support-1234
And you can move point on support-* and press C-c RET (bug-reference-push-button) to open it.

I have several .org files, and I'd like to be able to create links between them using an ID. I am using DOIs as unique identifiers. I can link within a file by using properties:
* Paper 1
:PROPERTIES:
:CUSTOM_ID: 10.1088/0953-8984/23/21/213001
:END:
* Paper 2
:PROPERTIES:
:CUSTOM_ID: 10.1038/nphys2935
See also [[#10.1088/0953-8984/23/21/213001]]
Is there a way to make the custom_id global, so I can reference it from another file?
I think that org-id is what I need to go further, but I've found the documentation a little confusing. I tried adding the following lines in my .emacs
;; Use global IDs
(require 'org-id)
(setq org-id-link-to-org-use-id use-existing)
;; Update ID file .org-id-locations on startup
(org-id-update-id-locations)
but the file .emacs.d/.org-id-locations only has nil.
It seems like global links won't be automatically generated (Assign IDs to every entry in Org-mode). I tried (with cursor on the heading) to use M-x org-id-get-create, but this does not seem to do anything.
EDIT: (Based on helpful comment)
Within one session, I can store and create links using M-x org-store-link while on the heading (Paper 1 in my example above). Then I can use M-x org-insert-link, and type the ID to insert the link. The link looks like [[id:10.1088/0953-8984/23/21/213001][Paper 1]]. But I am running into two problems: (1) I'd like the ids to be stored automatically. (2) The links don't work when I close and re-open the file.
EDIT: A related question:
https://emacs.stackexchange.com/questions/2186/have-org-modes-exported-html-use-custom-id-when-linking-to-sub-sections-in-toc
So here's the solution I came up with.
In my .emacs configuration, I have kept the same settings as in my question:
(require 'org-id)
(setq org-id-link-to-org-use-id use-existing)
;; Update ID file on startup
(org-id-update-id-locations)
The files need to be part of the agenda list (or added to the list of additional files using org-id-extra-files (See org-id documentation))
Use ID instead of CUSTOM_ID in the PROPERTIES drawer:
* Paper 1
:PROPERTIES:
:ID: 10.1088/0953-8984/23/21/213001
:END:
Each ID needs to be created (if necessary; in my case I already have them), and a link added to the ID file (links are stored in .emacs.d/.org-id-locations). This is done using org-id-get-create: with the cursor on the heading, call it using
M-x org-id-get-create
Link to an ID using [[id:10.1088/0953-8984/23/21/213001][Paper 1]].
I have to think a little bit more about when I'd like the ID to be created; I can automate the process by tying the ID storing to another function that I'll do to all the headings.
I am new to org-mode (using it under evil) and been using it as a very nice ASCII-based TODO with scheduled times and completion dates. I have a simple question - and in my case, I think an image is worth 1000 words...
Look at the image below, in the line that starts with "Merge button: ...." - i.e the one that I've split to two lines - with the continuation line starting with "click after..."
After hitting TAB to open the action tree node, the continuation line is colored in grey - as if it's not a part of the task in question:
This is further verified if I mark the task as DONE (shift-rightCursor): The DONE marker is placed below my task line, not below my continuation line - as if the continuation line is on its own:
I am probably missing something obvious - any help will be most appreciated.
In a word, it's the Design.
You could think like this:
The headline (first line) is the title of a task, the rest are contents/description or sub tasks.
The text at issue in the question of the original poster is what I generally refer to as the notes section of a task. By design, org-mode does not assign a particular highlighting of the notes section -- i.e., the default font for text will be used.
However, all is not lost. It is possible to change the default font for a particular buffer using the face-remapping-alist and setting it as a local variable. The following example uses a cyan foreground color, but it can be just about anything: http://www.gnu.org/software/emacs/manual/html_node/elisp/Face-Attributes.html I'm not certain when setq-local was introduced, but it is available in a current version of Emacs Trunk and may be available in earlier versions of Emacs.
(defun my-org-notes-face-function ()
(interactive)
(setq-local face-remapping-alist '(
(default (:foreground "cyan")))))
(add-hook 'org-mode-hook 'my-org-notes-face-function)
I use Emacs Org mode to deal with my daily staffs. Now I use Emacs to manage some research papers. When reading the papers, I would like to take some notes as the following using the shortcut key C-c C-z or only z in the Agenda View.
When taking a new note it looks like this:
However, after completing the note taking with C-c C-c, the note is stored in the LOGBOOK under where it was taken:
The first problem is that the note itself is not highlight. The second problem is that, if I would like to revise this note, I do not know how to display it as when it was taken(just as in the first picture above, in a new buffer with highlight). It seems that I could only revise this note under the "Note taken on ..." line with no highlight plain text.
However, I am not pleased with this editing method since it should be as the same as the first picture, i.e., when the note was first created.
Thanks for your attention and help.
In addition to using subtasks (as discussed in the comments underneath the initial question in this thread), here is an alternative approach that places the notes at the tail end of a task without any blank lines between sentences. The stock org-mode has the ability to handle this -- i.e., no modifications are required (other than keywords and priority settings)

I decided that I was ready to try something new, after a few years of using gEdit for most of my coding needs, and try to learn using Emacs. I knew this would be difficult, as I have heard how complex Emacs can be, but I was lured by its power. The hardest thing has been getting used to writing ELisp in the .emacs file to change things about the editor. I can't currently do it myself, but I have found a few helpful snippets here and there to change some options.
One thing I have been having a lot of problems with is getting Emacs to remember the text I have selected after a command. For instance, I commonly highlight a section of code to mass indent it. However, if I do this in Emacs, it will move the selected text only once before unselecting all of the text. Does anyone know a way around this?
Anyway, I apologize for what seems to me to be an easy question, but after an hour of Google searching and looking around here on SO, I thought it was worth asking. I have a few more questions about Emacs, but I will save them and ask separately after I get this straightened out. Thanks!
UPDATE
A few people have asked about what mod I am using and what type of text I am entering. While I don't know much about Emacs modes, I am editing a pure text file at the moment. Something like this:
Hello, I am a simple text file
that is made up of three separate
lines.
If I highlight all three lines and hit TAB, I get this:
Hello, I am a simple text file
that is made up of three separate
lines.
This is great, however, if I use C-x C-x like some suggest below to reselect the text and hit TAB again, I get this:
Hello, I am a simple text file
that is made up of three separate
lines.
I hope this helps!
FWIW, here is the reason for the behaviour of your newly-added example. (I'm not 'solving' the issue here, but I'm posting it to demystify what you're seeing.)
This was determined with emacs -q which disables my customisations, so the following is default behaviour for emacs 23.2.
You are in text-mode. You should see (Text) or similar in the mode line at the bottom of the screen, and C-h m will tell you (under the list of minor modes) "Text mode: Major mode for editing text written for humans to read." Emacs decides (by way of the auto-mode-alist variable) that it should switch to text-mode if you visit a filename matching certain extensions (such as .txt).
In text-mode pressing TAB with a region highlighted causes indent-according-to-mode to be called on each line of the region in sequence. The slightly convoluted path to finding this out starts at C-h k TAB, which tells us that TAB is bound to indent-for-tab-command, which in this instance calls indent-region -- that function name is not stated explicitly in the help, but can be seen in the code -- which checks the buffer-local indent-region-function variable, which is nil, and: "A value of nil means really run indent-according-to-mode on each line."
indent-according-to-mode checks the indent-line-function variable, which has the buffer-local value indent-relative.
Use C-h f indent-relative RET to see the help for this function. (Read this).
Although you probably won't yet have had the experience to know how to check all that (or necessarily even want to!), and fully understand everything it tells you, this is an example of how the self-documenting aspect of Emacs enables a user to figure out what is going on (which then makes it feasible to change things). I essentially just used C-h k (describe-key), C-h f (describe-function), and C-h v (describe-variable) to follow the documentation. Looking at the source code for indent-for-tab-command was as simple as clicking the file name shown as part of its help page.
I suggest doing the following to help see what is happening when indent-relative runs on each line:
M-x set-variable x-stretch-cursor t
M-x set-variable ruler-mode-show-tab-stops t
M-x ruler-mode
Now for each line in turn, put the cursor at the very start of the line and press TAB. You'll end up with all three lines indented to the first tab-stop ('T' in the ruler).
Now repeat this -- again, ensure you are at the very start of each line, in front of the existing indentation.
The first character of the first line (which is currently a tab) is once again indented to the first tab-stop, as there is no preceding line for it to examine.
Next, the first character of the second line is indented to match the position of the first non-white-space character of the preceding line. Because the first character of the second line is also a tab, the actual text of the second line is pushed one tab further along.
The third line follows suit. Its first tab character is lined up with the first non-white-space character of the second line, with the same relative effect as before, giving you the final state in your example.
To emphasise, note what happens if you now put enter the line "a b c" above the existing lines, then move back to the start of the next line (what was previously the first line) and press TAB. The first tab character will now be indented in line with the 'b'. Provided that the indent-tabs-mode variable is true (meaning you have actual tab characters), then this will have no practical effect on the position of the words in the line, as 'indenting' a tab with spaces will not have an effect until the number of spaces exceeds the width of the tab (but that's another kettle of fish entirely!)
All this really means is that text-mode in Emacs doesn't behave the way you'd like it to in this situation. Other major modes can do completely different things when you press TAB, of course.
As is invariably the case with Emacs, things you don't like can be changed or circumvented with elisp. Some searching (especially at the Emacs Wiki) will frequently turn up useful solutions to problems you encounter.
Try typing C-x C-x after Emacs unselects it.
Then, instead of hitting tab (I never knew that tab does what you said! That's totally whacked.), do M-8 C-x C-i. Pity it's so many keys, but it ought to do what you want -- namely, shove everything over 8 columns. Obviously replace the M-8 with something else if you want some other number of columns.
What I usually do is simply type C-x C-x (exchange-point-and-mark) after a command that deactives the region.
How are you indenting, and in which mode?
The indentation rules in any programming mode should generally just get it right. (If they don't, that's probably more indicative that you want to configure the rules for that mode differently, but I suspect that's a different question which has been asked already).
If you're in text-mode or similar and just using TAB, then I can see the problem.
Note that if you're using indent-rigidly (C-x C-i, or C-x TAB which is the same thing) then you can repeatedly indent the same region simply by repeating the command, even if the highlighting has disappeared from view.
You can also use a prefix arg to indent-rigidly to make it indent many times. e.g. C-u C-u C-x C-i (easier to type than it looks) will indent 16 spaces (4 x 4, as the prefix arg defaults to 4, and it multiplies on each repeat). Similarly, M-8 C-x C-i indents 8 spaces. This is fine in some circumstances, and way too cumbersome in others.
Personally I suggest putting (cua-selection-mode 1) into your .emacs and using that for rigid indentation. Trey Jackson made a handy blog about it. With this, you can C-RET to start rectangle selection, down as many lines as you need, TAB repeatedly to indent the lines, and C-RET to exit the mode.
While the rectangle is active, RET cycles through the corners. For left-hand corners, typing inserts in front. For right-hand corners, typing inserts after. For the single-column rectangle, bottom counts as 'left' and top counts as 'right' for this purpose.
Trey's blog lists all the available features (or look in the source file: cua-base.el)
Be warned that indentation in Emacs is generally an unexpectedly complicated topic.
You can do this with something like the following:
(add-hook 'text-mode-hook (lambda ()
(set (make-local-variable 'indent-region-function)
(lambda (s e)
(indent-rigidly s e tab-width)))))
Then selecting a region and hitting TAB. will indent the region by a tab-width. You can then exchange point and mark with C-x C-x and hit TAB again to repeat.
I do, however, agree with the previous answers that suggest using indent-rigidly directly.
