177.Cm vt_vga .
178If a KMS
179.Pq Kernel Mode Switching
180video driver is available, the display is switched to high resolution
181and the KMS driver takes over.
182When a KMS driver is not available,

206.Sh KEYBOARD SYSCTL TUNABLES
207These settings control whether certain special key combinations are enabled or

209The specific key combinations can be configured by using a
