I recently started using Helm and am really enjoying it. However, I use emacs to write a lot of LaTeX. When I cite articles, I often need to cite several in the same cite macro - I could search my bibliography file for two separate entries very easily, using RefTex:
citekey1\|citekey2
However when helm mode is on, this no longer works. I can still search for single articles but not multiple articles. How can I do the above in helm?
