I've read quite a few questions and answers on this web site but none helps me to resolve my problem. I am using \ref and \eqref commands most often. After installing and re-installing the latest version of TeXstudio (2.10.0, 5.5.0), in some files the command \ref offers a list of available labels, but in some it gives an empty list although the file itself contains plenty of labels. At the same time, \eqref does not work at all. I would be grateful if somebody could help! Thanks!
[Tex/LaTex] TeXstudio: \ref and \eqref auto-completion

For the case you've given ] is inserted, because \item[text] is in the completer. Once you've typed \item[ this is the only possible choice in the completer. You may disable this by unchecking Configure -> Completion -> Autocomplete Common Prefix.
For that, you will have to make use of a custom .cwl file (which, afaik, requires a recent version of TeXstudio).
Create a file, let's say mycwl.cwl, in either %appdata%\texstudio\completion\user or .config/texstudio/completion/user according to your system.
In it, place the following line:
\alternative{label}#r
and save it. Technically, you can put anything meaningful in the argument, but some terms are reserved and have special meaning. And, as you wish TeXstudio to recognize a label there, you require one of those, namely label. The comment at the end of the line tells TeXstudio what kind of command yours is. #r stands for this command declares a reference like "\ref{key}". For further commands, just add a new line to your mycwl.cwl.
Then, in TeXstudio, go to Options -> Configure TeXstudio -> Completion and check mycwl.cwl on the list (crucial). And that's about it.
For more details on customizing autocompletion with cwl files, check the TeXstudio manual, section "4.13 Description of the cwl format".
A tip: If the manual seems complicated, and you'd like to emulate the behavior of some command's autocompletion you like, you might want to download the sourcecode tarball at http://texstudio.sourceforge.net/, unpack it and look at the built-in cwl files in the "completion" folder. From there, you can proceed by means of examples of your commands of interest.

When
\refoffers the list of labels but\eqrefdoes not, add\eqref{key}#rto your.cwlfile. Then save it, close TeXstudio and again open TeXstudio.I found it here and it solved the problem for me. Unfortunately, I don't have a link to an explanation of
keyand#ror of.cwl's in general.
