Keyboard shortcuts need modifier keys

Keyboard shortcuts in web UIs should always require modifier keys like Ctrl or Cmd to be accessible. WCAG 2.1 Success Criterion 2.1.4 prohibits single-character shortcuts (letters, numbers, punctuation, or symbols — collectively 'printing characters') because they can be accidentally triggered by speech input users or those with fine motor impairments. Exceptions exist if shortcuts can be turned off, remapped by users, or only activate when a specific component has focus. The slash (/) character counts as a printing character and should not be used as a standalone shortcut.
