Usually, if your computer has a hotkey sequence for killing the wireless
interface, it'll be labelled on the keys (perhaps with a diagram of a
wire with radiating curved lines around it - as an diagram for an
antenna).  It's common for there to be a dedicated switch or button,
rather than using the keyboard.  On some laptops, I've seen a completely
unlabelled button with a light on it as the kill switch.  Mine has a
black slider switch, on the side, with black embossed labelling (very
Douglas Adams).

Usually the kill switch is an absolute control - it'll kill the
wireless, and nothing the computer does can turn it back on.  The kill
switch has to be turned on again.  In some cases, it's a simple as a
mechanical switch that turns off the power to the wireless hardware.

There's a chance that the wireless, once disabled, won't restart without
some fiddling.  I've had that happen, it requiring turning off, waiting
half a minute, turning on, waiting, restarting the NetworkManager
service, waiting, before something woke up again.

Funny how computers can do millions of computations a second, but take
half a minute to initialise some hardware...
