I have a very weird situation with my tags file not working as expected. My tag file is sorted case-insensitively (starts with
!_TAG_FILE_SORTED\t2\t/foldcase/), and ignorecase is set.
When I put my cursor over
Word_I_Am_Looking_For and hit
CTRL-] I get
E257: cstag: tag not found. However when I type
:ta /<C-W> to fill out
:ta /Word_I_Am_Looking_For it finds my tag no problem.
To diagnose the issue I opened the tag file itself and jumped to the line in question. When I turned on
set list I saw:
Word_I_Am_Looking_For^I/path/to/word/i/am/looking/for^I/\%123l\%456c/$ which looks right to me.
What is causing vim to miss the tag?
