When you type ^], Vim looks at the character under the cursor and the characters next to it and tries to identify a sequence of characters including the one under the cursor that form a keyword, by Vim's definition of a keyword. Vim then tries to find that keyword in its list of tags. Vim's definition of a keyword is a sequence of characters from the set in the 'iskeyword' option. Vim uses this definition for a lot of its commands, not just those related to tags. For example, it uses that definition to recognize words when executing w to move to the next word or diw to delete the word the cursor is on. Consequently, Vim's default definition of 'iskeyword' is set to correspond to a word as commonly used in text or a keyword as used in most programming languages: a sequence of characters from the set of alphanumeric characters and underscore. When you move Vim's cursor to the start of the Lua identifier TaskHandler.prizeTask and type ^], Vim will try to find the keyword under the cursor, which by its normal definition is TaskHandler. TaskHandler is not a tag, though, so the command fails. Similarly, Vim recognizes prizeTask as a keyword but it is not a tag, either. You can make this work by adding . to the set of characters that Vim recognizes as part of a keyword, that is, by adding . to 'iskeyword': :set iskeyword+=. Now Vim will recognize TaskHandler.prizeTask as a single keyword and will

[Time passes while I do other work and think some more.] I just appended those lines from your tags file to mine and added tabs between the fields. Typing ^] over TaskHandler or prizeTask resulted in E426. Then I executed :set iskeyword+=. and tried again. This time I got this error: E429: File .\init\taskHandler.lua does not exist So I think that's the problem: you need to have . in your 'iskeyword' option for Lua files.
