You find here commands that help editing the score. These commands are not directly related to the music, but instead to the structure.
You can use this command if needed to disable and enable point-and-click in the generated PDF file. By default point-and-click is enabled, and makes the PDF file large.
Using the hyphenation tool you can automatically hyphenate lyrics (using OpenOffice dictionaries) and change accents.
To invoke the lyrics tool select the text you want to hyphenate and invoke >>
To use the hyphenation features you must have the
OpenOffice.org hyphenation dictionaries
somewhere. These are files beginning with hyph_
and having the .dic extension. From OpenOffice 3
the dictionaries are in extension files with .oxt filename extension.
To use them in LilyPondTool, just create a folder somewhere, unzip the
.oxt files to there (they are simple ZIP files, so you an extract them
with all unzipping tool), and set that folder in LilyPondTool options
as the OpenOffice.org dictionary folder.
Note that OpenOffice's hyphenation engine is not very suitable for this purpose, so it is almost sure that you must correct the hyphenation at some places.
