It’s mapped to e.g. VK_CANCEL on Windows:
❯ git grep Key_Cancel
dist/changes-4.2.0:1246: * Added several missing keys to the Key enum:
Key_Cancel, Key_Printer,
src/corelib/global/qnamespace.h:1060: Key_Cancel = 0x01020001,
src/corelib/global/qnamespace.qdoc:1829: \value Key_Cancel
src/gui/kernel/qkeysequence.cpp:693: { Qt::Key_Cancel,
QT_TRANSLATE_NOOP("QShortcut", "Cancel") },
src/gui/platform/unix/qxkbcommon.cpp:163: Xkb2Qt<XKB_KEY_Cancel,
Qt::Key_Cancel>,
src/platformsupport/input/evdevkeyboard/qevdevkeyboard_defaultmap_p.h:664: {
KEY_CANCEL, 0xffff, Qt::Key_Cancel, 0x00, 0x00, 0x0000 },
src/plugins/platforms/windows/qwindowskeymapper.cpp:214: Qt::Key_Cancel,
// 3 0x03 VK_CANCEL | Control-Break processing
Don’t know what physical key would produce this.
