Jean-Marc Lasgouttes Sun, 01 Feb 2015 14:44:19 -0800 That's terribly weird. Could this be completion playing tricks? Although I do not see this happening.Can you give us details (LyX version, platform...). We never had a report like this one.If you want to find all these occurrences in your document, I guess it is possible with advanced search and replace and regular expressions.
Using a regular expression worked well a treat to find the double words. I had a feeling I could programmatically use the feature but didn't know how to implement the search like that. I have now removed all that were in the master document and will now see if I can trace when and how any new occurrences are introduced. For others reference, the way to find double words in the Advanced Find and Replace is with a user defined regular expression that contains: [[:space:]]([[:alpha:]]+)[[:space:]]\1[[:space:]] The code was found buried in the 2.1.1 User guide. Re. The actual double word bug. I'm updating to LyX 2.1.2 and hoping that the bug has been inadvertently fixed. But if it hasn't, now that I have been able to find the double words and remove them I should be able to tell if the duplication is related to new keystrokes or whether it is the bug is more spurious.
