Keyboard

This page outlines keyboard behavior specific to different host operating systems, real keyboards and emulated machines.

Host systems

Windows

  • Multimedia keys such as Volume Up/Down cannot be passed through to the emulated machine due to a Windows limitation.
  • System-wide key remapping through the Scancode Map registry key (as performed by applications such as SharpKeys) is fully supported.

macOS

  • Apple keyboards with European or other ISO layouts may have the key below Esc and the key to the right of Left Shift switch places in the emulated machine, due to a hardware quirk in many of those keyboards (both internal and external) and a limitation in the way macOS corrects it.
  • The Num = key is only usable in operating systems which recognize that key on Microsoft PS/2 multimedia keyboards.
  • Mac special keys are mapped to their PC equivalents where possible:
Emulated key Host key
Windows Command
Alt Option
Print Screen F13
Scroll Lock F14
Pause F15
Insert

Command + Fn + Delete (MacBook and tenkeyless keyboards)

Command + Forward Delete (full size keyboards)
Num Lock Clear

Linux

  • The xkbcommon library is used to accurately map physical keys to the emulated keyboard on both X11 and Wayland. When compiling 86Box from source, make sure the development files for libxkbcommon and libxkbcommon-x11 are installed, as this is an optional build component.

Special keys

Some machines provide additional function or otherwise special keys on top of the standard PC layout. Those keys are mapped to ones present on modern keyboards within reason.

Olivetti

The Olivetti M series special keys are mapped as such:

Emulated key Host key
CLEAR Page Up
BREAK Page Down
SCR PRT Print Screen
HELP Menu
00 Left Windows
F13 Insert
F14 Home
F15 Del
F16 End
F17 Right Alt
F18 Right Win

Toshiba

The Toshiba T1000 series function keys can be accessed by holding Right Alt or Right Ctrl:

Function Right Alt/Ctrl +
Show/hide numeric keypad overlay Num Lock
Change internal display font Right
Use internal display Home
Use external display End
Turbo mode on (T1200) Page Up
Turbo mode off (T1200) Page Down
Show/hide pop-up window (T1200) Print Screen
