LibreOffice offers a powerful search and replace option of regular expressions – like, for instance, tabs, soft line breaks and empty paragraphs – based on the powerful International Components for Unicode (ICU) Regular Expressions engine. A complete list of the regular expressions can be found on the ICU Project website.

A list of the regular expressions most used by LibreOffice can be accessed via the dialog windows which opens when you enter Edit > Find & Replace… Clicking on the Other Options… arrow, you expand the list, from which you can select Regular Expressions. Hitting the Help button opens the relevant help page.

Half way down the page, under Regular Expression, you can find a link to the list. Additional links at the end of the page provide further info on the topic.

Libreoffice offers a number of different icon sets, which can be selected from the menu Tools > Options > LibreOffice > View. The default Linux icon set is called Human, while the default Windows icon set is called Tango.

Together with Galaxy and Oxygen, they have been the available options for quite a long time (although there have been several improvements to the design of the icons).

The modern Breeze and the monochromatic Sifr (the default icon set on MacOS X) are the new additions. Sifr has been introduced with LibreOffice 4.2, while Breeze has been announced with LibreOffice 5.0.

Last, but not least, there is a specific High Contrast icon set for specific applications.

Hybrid PDFs are a peculiar feature of LibreOffice, and are extremely handy for interoperability. They are standard PDF files, which embed a standard ODF document.

Because of this characteristic, although they have a PDF extension they can be opened by LibreOffice as fully editable documents (please note that they cannot be opened with a double click on the icon, as any regular ODF document, but they must be opened from within LibreOffice by using the menu File > Open).

The process to create a Hybrid PDF is extremely simple. In fact, Hybrid PDFs are one of the options of the menu File > Export as PDF…, which is used to create any kind of PDF file – PDF, PDF/A, signed PDF, Hybrid PDF – with LibreOffice.

Once the dialog window is open, the Hybrid PDF option is the first one on the right hand column, and can be combined with every other PDF option (which will be recognized by any PDF reader, independently from the fact that the file embeds the ODF document).

LibreOffice Writer was born – as StarWriter – to produce lengthy documents, such as thesis and relations, and as such offers a number of specific features in this area. Two of the most important are Templates and Styles, which facilitate the creation of good looking documents, and make it easier to reproduce a standard document once the layout – including Styles – has been defined and consolidated. LibreOffice offers an almost hidden feature to produce a Template, which can be accessed from the menu File > Send > Create Master Document. This opens a “save as…” dialog window, which allows to save the open document as a Template.

Today, a very simple tip, for all those people who are using LibreOffice and own a mouse with a scroll wheel (today, most mice have a scroll wheel, or are able to mimic the behavior of a scroll wheel).

LibreOffice allows to zoom a document from 20% (very tiny) to 600% (very large), independently from the application (Writer, Calc, Impress and Draw), by pressing the Control key on the keyboard and rotating the scroll wheel. You go from 20% to 600% by rotating the wheel forward, and from 600% to 20% by rotating the wheel backward.

Of course, the zoom speed is strictly related to a number of factors, so might not be as quick as the user would like. Start gently, and increase the speed with time, considering that a large document or a small RAM may slow down the process.

LibreOffice has a comprehensive AutoCorrect feature, which can be accessed from the menu Tools > AutoCorrect Options… The command opens a dialog window with five tabs: Replace, Exceptions, Options, Localized Options, and Word Completion. Replace provides a list of symbols and words which might be entered using the wrong character or misspelled, and will be corrected automatically once entered. The list can be improved by the user, with the addition of other words. Exceptions provides a list of the words which do not follow the rule, and can also be improved by the user with the addition of other words.

Options are pre-configured, and are correcting some of the most common typing mistakes, such as two initial capitals, double spaces, and empty paragraphs. Localized Options (no screenshot) provides some additions to the previous tab, related to specific language issues. Last, Word Completion provides a list of words which can be autocompleted by LibreOffice once the feature has been enabled.
