# Font & Colors

Set the font preferences and apply color schemes for syntax highlighting, diff editor, and code analysis results.

To set editor font and colors, select Preferences > Text Editor > Font & Colors.

## Configuring Fonts

You can select the font family and size. You can specify a zoom setting in percentage for viewing the text. You can also zoom in or out by selecting Ctrl + + or Ctrl+-, or by selecting Ctrl while rotating the mouse wheel. To disable the mouse wheel function, select Preferences > Text Editor > Behavior and clear Enable scroll wheel zooming.

To improve the readability of text in the editor, adjust the line spacing in the Line spacing field.

Antialiasing is used by default to make text look smoother and more readable on the screen. Clear Antialias to turn off antialiasing.
