html - Capturing the ESC key using Javascript only -

i have custom video play it's own controls. have script create changes controls when user enters , exists fullscreen. problem when exit fullscreen using esc key instead of button, style changes controls not reverted back. need ensure exiting fullscreen using esc or button result in same behaviour.

css:

function togglefullscreen() { elem = document.getelementbyid("video_container"); var db = document.getelementbyid("defaultbar"); var ctrl = document.getelementbyid("controls"); if (!document.fullscreenelement && // alternative standard method !document.mozfullscreenelement && !document.webkitfullscreenelement) { // current working methods if (document.documentelement.requestfullscreen) { ctrl.style.width = '50%'; ctrl.style.left = '25%'; full.firstchild.src = ('images/icons/unfull.png'); elem.requestfullscreen(); } else if (document.documentelement.mozrequestfullscreen) { full.firstchild.src = 'images/icons/unfull.png'; ctrl.style.width = '50%'; ctrl.style.left = '25%'; elem.mozrequestfullscreen(); } else if (document.documentelement.webkitrequestfullscreen) { ctrl.style.width = '50%'; ctrl.style.left = '25%'; full.firstchild.src = 'images/icons/unfull.png'; elem.webkitrequestfullscreen(); } } else if (document.exitfullscreen) { full.firstchild.src = 'images/icons/full.png'; ctrl.style.width = '100%'; ctrl.style.left = '0'; document.exitfullscreen(); } else if (document.mozcancelfullscreen) { full.firstchild.src = 'images/icons/full.png'; ctrl.style.width = '100%'; ctrl.style.left = '0'; document.mozcancelfullscreen(); } else if (document.webkitcancelfullscreen) { ctrl.style.width = '100%'; ctrl.style.left = '0'; full.firstchild.src = 'images/icons/full.png'; document.webkitcancelfullscreen(); } }

it sounds want attach keypress event document. ought trick.

document.onkeypress = function(evt) { evt = evt || window.event; if (evt.keycode == 27) { alert("esc pressed"); } };

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
