For example,
      if using handwriting to enter text, the input technique (handwriting) requires path-dependent
      input but the underlying function (text input) does not. Note 2 This does not forbid and should not discourage providing mouse input or other input
      methods in addition to keyboard operation. Success Criterion 2.1.2 No Keyboard Trap Understanding No Keyboard Trap | How to Meet No Keyboard Trap (Level A) If keyboard focus can be moved to a component of the page using a keyboard interface , then focus can be moved away from that component using only a keyboard interface,
      and, if it requires more than unmodified arrow or tab keys or other standard exit
      methods, the user is advised of the method for moving focus away. Note Since any content that does not meet this success criterion can interfere with a user's
      ability to use the whole page, all content on the Web page (whether it is used to
      meet other success criteria or not) must meet this success criterion. See Conformance Requirement 5: Non-Interference .
