toggle full screen by clicking or pointing at the top

Enter full screen by left clicking on the page. Exit full screen by pointing at the top of the screen. Since: https://superuser.com/questions/1368977/how-to-re-enable-proper-full-screen-mode-in-chrome-with-display-of-toolbar-on-ho https://groups.google.com/a/chromium.org/g/chromium-discuss/c/f9r8ZsaMm9o/m/43l1YN1KCwAJ https://support.google.com/chrome/thread/67228761/how-to-show-tabs-bar-in-chrome-full-screen-mode-just-like-in-firefox. Why enter full screen by left clicking on the page, why don't just use the mouseenter event, no need to click? document.documentElement.requestFullscreen() needs a user gesture, to avoid abuse. But: chrome://flags/#automatic-fullscreen-content-setting https://chromestatus.com/feature/6218822004768768, the .js would be: function $(){document.addEventListener("mouseenter",()=>{document.documentElement.requestFullscreen() _=new AbortController() addEventListener("mousemove",e=>{if(e.y==0){document.exitFullscreen() _.abort() $()}},{signal:_.signal})},{once:true})} $()
