javascript - Simulating keypress events to navigate a website -

i'm working myo. it's armband connects computer via bluetooth. can detect movement of hand , can detect several gestures, such 'wave_left' , 'wave_right' , 'fingers_spread', 'fist' mainly. i've write javascript disabled persons can navigate website using myo. implement this, want map key press events myo gestures.

wave_left => tab

wave_right => shift + tab

fingers_spread => backspace

fist => enter

now here's code

<script src='http://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.6.0/underscore-min.js'></script> <script src="https://cdn.rawgit.com/stolksdorf/myo.js/master/myo.js" ></script> <script src="https://cdn.rawgit.com/stolksdorf/myo.js/master/experimental/myo.experimental.js" ></script> 

myo events handled here following

var myo = myo.create(0);  myo.on('arm_recognized', function(){     console.log('arm found!', this.id); }); myo.on('arm_lost', function(){     console.log('arm lost', this.id); }); myo.on('wave_left', function(){     console.log('wave left!');     // tab key press event triggered }); myo.on('wave_right', function(){     console.log('wave right!');     // shift + tab key press event triggered  }); myo.on('fingers_spread', function(){     console.log('spread!');     // backspace key press triggered }); myo.on('fist', function(){     console.log('fist');     // enter key press triggered  }); myo.on('connected', function(){  }); myo.on('bluetooth_strength', function(bts){     console.log(width); }); myo.on('double_tap', function(){     console.log('double tap') ; }); myo.on('gyroscope', function(data){  }); 

i've searched internet. simulating tab key press, people suggested use $('some_element').next().focus() , want native tab key press. this post says it's not possible because of security issue. post 2009, , html5 has progressed lot after then. possible trigger keypress event of special keys , native result? if possible, should do? in advance!
