If I have a heading called "heading1", I can link to it within the same org file with [[heading1]], but cannot link to it with [[Heading1]]. Is there a way to make links case insensitive?

  • The searches work in a case insensitive way inside of my org test buffer. They also are not affected by the case-fold-search variable. Does the link not work for you inside of an org mode buffer, or you have that problem in some exported document? – dfeich Feb 20 '16 at 8:46
  • I am talking about org-mode buffer. I am not talking about search, I am asking about following internal org links and case sensitivity. Please original question and let me know if I there is something I need to clarify about it. – chukcha2 Feb 21 '16 at 17:24

    internal links are implemented as a search in the buffer (q.v. orgmode.org/manual/Internal-links.html). Contrary to your tests, in my own org buffers a link like [[heading1]] works in a case-insensitive way... so this is why I was asking. Maybe something in your config makes the search case sensitive. – dfeich Feb 21 '16 at 22:58
  • I tried starting emacs with -Q option to avoid loading any custom configuration. When I use C-c C-o with [[heading1]], the cursor jumps to heading1. When I use C-c C-o with [[Heading1]], I get prompted with No match - create this as a new heading? (y or n) My emacs version is 24.3.1 (running on Ubuntu). My org version 7.9.3f. – chukcha2 Feb 23 '16 at 1:57

    Ok... it is due to your Org version. I tested now with your same emacs version and default org. There I get the same behavior. Emacs 24.3.1 with the org version 8.3.3 from MELPA shows the behavior you want and jumps to links in a case insensitive way. You should upgrade Org... even more so, since Org >=8 brings a plethora of improvements and a completely new exporter (Bastien just posted the release of 8.3.4 btw). – dfeich Feb 23 '16 at 6:16

Looking at the internal link section in the Org manual, it doesn't look like it is possible. You can, however, use [[heading1][Heading1]] if you want to make the description a different case from the link target.

  • Yep, thank you, I saw that too. I was hoping there was some undocumented way. Or perhaps I could ask for this feature to be added to org mode (can't implement it myself). – chukcha2 Feb 21 '16 at 17:26

Per @dfeich suggestion I installed org from ELPA and internal links became case insensitive.

The version that I installed from ELPA is 8.3.4 (20160222). The built in version that I had before was 7.9.3f.
