What this video covers
A keyboard trap is when focus enters a spot but can't exit via keyboard - a widget, embed or dialog that captures Tab, leaving keyboard or switch users stranded and unable to reach the rest of the page. For someone who can't use a mouse, it’s not an annoyance; it’s a dead end that can make the whole page unusable.
Tab into the trap and Tab again, and again - and focus just cycled inside, with the rest of the page out of reach. For a mouse user that's a shrug; for someone navigating by keyboard alone it's being stuck in a room with no handle. Pressing Escape let you out - which is exactly the escape hatch a real trap is missing.
