58The

62.Bl -item -offset indent
63.It
64Unicode UTF-8 text with double-width characters.
65.It
66Large font maps in graphics mode, including support for Asian
67character sets.
68.It
69Graphics-mode consoles.
70.It
71Integration with
72KMS
73.Pq Kernel Mode Setting
74video drivers for switching between the
75.Em X Window System
76and virtual terminals.
77.El
78.Ss Virtual Terminals
79Multiple virtual terminals are provided on a single computer.
80Up to sixteen virtual terminals can be defined.
81A single virtual terminal is connected to the screen and keyboard
82at a time.
83Key combinations are used to select a virtual terminal.
84Alt-F1 through Alt-F12 correspond to the first twelve virtual terminals.
85If more than twelve virtual terminals are created, Shift-Alt-F1 through
86Shift-Alt-F4 are used to switch to the additional terminals.
87.Ss Copying and Pasting Text with a Mouse
88Copying and pasting text from the screen with a mouse is supported.
89Press and hold down mouse button 1, usually the left button, while
90moving the mouse to select text.
91Selected text is highlighted with reversed foreground and background
92colors.
93To select more text after releasing mouse button 1, press mouse button
943, usually the right button.
95To paste text that has been selected, press mouse button 2, usually the
96middle button.
97The text is entered as if it were typed at the keyboard.
98The
99.Dv VT_TWOBUTTON_MOUSE
100kernel option can be used with mice that only have two buttons.
101Setting this option makes the second mouse button into the
102paste button.
103See
104.Xr moused 8
105for more information.
106.Ss Scrolling Back
107Output that has scrolled off the screen can be reviewed by pressing the
108Scroll Lock key, then scrolling up and down with the arrow keys.
109The Page Up and Page Down keys scroll up or down a full screen at a
110time.
111The Home and End keys jump to the beginning or end of the scrollback
112buffer.
113When finished reviewing, press the Scroll Lock key again to return to
114normal use.
