Keyboard Navigation and Focus Order

Many users rely on keyboard navigation:

• Motor disabilities — cannot use a mouse
• Power users — prefer keyboard shortcuts
• Screen reader users — navigate entirely by keyboard
• Switch access users — use buttons that simulate key presses

These HTML elements are keyboard-focusable by default:

• <a href> — Tab moves to it, Enter activates it
• <button> — Tab moves to it, Enter/Space activates it
• <input>, <textarea>, <select> — Tab moves to them
• <details> / <summary> — Tab + Enter
