LibreOffice is designed with great attention to accessibility, to make the suite convenient and comfortable to use, and to cater to users with special needs. You can also read other useful accessibility information on our wiki. If you find shortcomings or gaps in the features or the information provided, please consider helping to improve it, by telling us via our mailing lists or by considering getting involved as a contributor to the project.

Keyboard Navigation

Full Keyboard Navigation and Control

Full keyboard navigation gives the users the ability to perform all input via a keyboard, without using a mouse or other pointing device.

The features that most notably enhance accessibility include:

  • Comprehensive definitions of keyboard shortcuts in the different applications;
  • Full keyboard access to toolbars;
  • Keyboard-enabled switching between document windows, menus, toolbars, modeless dialogs and floating windows;
  • Enhanced keyboard navigation in text documents and online help to navigate and activate hyperlinks;
  • Menu and toolbar items for accessing functions which where only accessible via mouse device;
  • Disabled menu items are displayed by default;
  • You can access help tips via keyboard;
  • You can set the duration for the display of help tips;
  • Keyboard access for Drawing Objects:
    • Drawing objects can be inserted via toolbar with default position and size;
    • Each handle of a drawing object can be selected and controlled via keyboard separately, so even polygon manipulation is possible;
  • Particular attention has been given to accessibility in dialog boxes, including:
    • the toolbar customization dialog;
    • extensive CSV import control for spreadsheets.



Colors and Fonts

Use of System Color Schemes, High Contrast

LibreOffice adapts to the color schemes and contrast display settings of the operating system.

In addition, LibreOffice offers additional settings for colors which are not specified in any system color schemes, as well as the possibility to overwrite colors from the current color scheme. You can also create and store your own color schemes in LibreOffice.

The help system respects the colors from the current color scheme, but also provides different predefined styles. Users can customize the formatting of the help content via the XSL transformation file, as well as via the custom style sheet file located in the help directory.

Automatic Text Color

All LibreOffice applications support automatic text color for documents and use this by default, so the text is always distinguishable from the background color.

The text will be displayed in the system text color. If this leads to dark text on a dark background, or bright text on a bright background, the text will switch to black or white (according to whichever provides better contrast).

For reading old or imported documents which use hard-formatted text colors, you can use the option "Use automatic font color for screen display". All text content as well as table borders and some other elements will be displayed in the automatic font color.

Icons and Bitmaps

LibreOffice has icon sets for small and large toolbar icons in normal and in high contrast mode, so the icons are more easily identifiable in the different modes.

All UI elements displaying a graphic offer an alternative graphic for high contrast mode.

LibreOffice automatically chooses the set of icons and graphics appropriate for the current system settings.

High Contrast Mode for Impress and Draw

Impress and Draw offer a high-contrast mode, in which objects are displayed without fill colors or text colors.

This mode will automatically be used when high contrast is chosen in the system settings. You can turn off this automatic detection in the LibreOffice options under “Accessibility “.

System Font

LibreOffice can use the operating system font for the user interface, so that LibreOffice appears in the same font as your other applications and can be manipulated via the system settings.

There is special handling to ensure that dialogs do not become larger than the screen when schemes with large fonts are chosen.

Other Legibility Features

  • Highlighted toolbar and menu items are easily perceptible;
  • There is distinct highlighting of current column and row in spreadsheets;
  • You can turn on/off animations for graphics and text.



Assistive Technology

API for Supporting Assistive Technologies

Assistive Technology (AT) tools such as screen readers and magnifiers, as well as other tools, connect to LibreOffice using the native accessibility APIs of the corresponding platform (Microsoft Active Accessibility API (MSAA)/IAccessible2 on Windows, AT-SPI2 on GNU/Linux, NSAccessibility on macOS).

LibreOffice UI elements and documents expose all the information about themselves and their contents via those accessibility APIs.

An enormous effort has been made to have UI elements and document contents fully support the accessibility interfaces; for example: providing text with attributes and character bounds information, and sending all the necessary notifications and providing names and descriptions of controls.

Some AT tools send key events to the applications, or simply control the mouse, so it makes no difference for the application if the input comes from a user or from an AT tool.

This way, a lot of AT tools such as simple on-screen keyboards, head mice, eye tracking devices and single switches can be used with LibreOffice.

Support for Comfortable Reading of Read-Only Documents

Screen reader users sometimes have difficulty reading read-only documents because they cannot navigate with the cursor through the document.

For this, there is the feature "Use text selection cursor in read-only text documents".

Other AT features

  • Floating windows, dialogs and menus are system windows;
  • Every individual drawing object can have a name;
  • All sample documents and templates are enhanced to provide names and descriptions for drawing objects.




Accessible Documentation

All user documentation is provided in ODT and PDF formats so users can use screen readers and magnifiers to read the documentation. For more information about user documentation, please visit the Documentation page on this site, or the Documentation page on our wiki.

All keyboard shortcuts are documented in the online help.

Accessible Online Help

The online help provides information on how to use all the accessibility features in LibreOffice.

The online help is accessible itself. Users can access it using screen readers, magnifiers and on-screen keyboards.
