Operation Manual

User Interface – Scaling
If the text in the help files or on the menus of the LibreOffice user interface is too small or too
large, you can change it by specifying a scaling factor. Sometimes a change here can have
unexpected results, depending on the screen fonts available on your system. However, it
does not affect the actual font size of the text in your documents.
User Interface – Icon size and style
The first box specifies the display size of toolbar icons (Automatic, Small, or Large). The
Automatic icon size option uses the setting for your operating system. The second box
specifies the icon style (theme); here the Automatic option uses an icon set compatible with
your operating system and choice of desktop: for example, KDE or Gnome on Linux.
User interface – Screen font anti-aliasing
(Not available in Windows.) Select this option to smooth the screen appearance of text. Enter
the smallest font size to apply anti-aliasing.
Mouse positioning
Specifies if and how the mouse pointer will be positioned in newly opened dialogs.
Middle mouse button
Defines the function of the middle mouse button.
• Automatic scrolling – dragging while pressing the middle mouse button shifts the view.
• Paste clipboard – pressing the middle mouse button inserts the contents of the
“Selection clipboard” at the cursor position.
The “Selection clipboard” is independent of the normal clipboard that you use by Edit >
Copy/Cut/Paste or their respective keyboard shortcuts. Clipboard and “Selection clipboard”
can contain different contents at the same time.
Function Clipboard Selection clipboard
Copy content Edit > Copy Ctrl+C Select text, table, or object.

the cursor position.
Clicking the middle mouse button pastes
at the mouse pointer position.
Pasting into another

The last marked selection is the content
of the selection clipboard.
Graphics output – Use hardware acceleration
Directly accesses hardware features of the graphical display adapter to improve the screen
display. Not supported on all operating systems and LibreOffice distributions.
Graphics output – Use anti-aliasing
Enables and disables anti-aliasing, which makes the display of most graphical objects look
smoother and with fewer artifacts. Not supported on all operating systems and LibreOffice
distributions.
Tip
Press Shift+Ctrl+R to restore or refresh the view of the current document after
changing the anti-aliasing settings, to see the effect.
