Level AWCAG 2.2
2.1.4 Character Key Shortcuts
Single-character keyboard shortcuts can be turned off, remapped, or limited to focus.
Why it matters
Speech input
Speech recognition software triggers shortcuts every time it dictates a character, breaking operation.
Accidental input
Single-key shortcuts cause unexpected behavior from unintended keystrokes.
Multilingual input
When using an IME, alphabet keys may be processed as shortcuts.
Customization
It is important that users can disable or remap shortcuts to fit their own environment.

Shortcut: S opens search
WCAG 2.1.4 requires single-character shortcuts to provide a way to disable them, a way to remap them, or an option to make them active only when focus is inside the component .
Understanding through personas
Watanabe (52) — Speech input user
Tremors make keyboard input difficult, so I dictate text with speech recognition. Every time I say 'search', the S key opens the search panel and my input disappears.
