@alexanderpann I tried out the fix from #560 but I don't think it fixes the problem. The problem is not with the slash but rather that the finder does not locate the available sheets for possible reference. I have attached what I am seeing even after applying the patch from #560 .

here is what I see with the reflective editor

Once I did add the referenced sheet via the reflective editor, I was unable to set the cell. Should the list of available cells for reference also show up in the CTRL-space menu? They don't for either the regular or the reflective editor.

Is it also an issue that I cannot get to the referenced cells via the found spreadsheet candidate?

I left a comment in #560 - I think @brucetrask is right and the PR does not fix this issue.

@sergej-koscejev Hi Sergej, Should we perhaps change the name of this issue since it is not related particularly to the "/" and may thus be misleading? Perhaps "Finder in sheets does not work" or something like that.

I think it's fine for now, the problem seems to be related to (keyboard) typing. I'd leave it up to Alexander to judge.
