Here is another possible bug of LilyPondTool, related to the
autocomplete feature.
Some Windows users reported that the stroke of the backslash key
produces automatic (and undesired) insertion of a previous defined
variable name, instead of a list of autocompletion candidates.
Then I have experienced this on linux as well, but now I cannot
reproduce it, I really don't get any autocompletion list of candidates
nor auto-undesired-insertion. So there seems to be something erratic
out there.
We use latest versions of java, jedit and lilypondtool.
