Features

The most important features includes:

• Works (almost) like gmail's page-scope, VIM-like, checkbox navigator
• Act's like a plug-in on an existing page. Just add code provided in the sample chapter above
• Also add's shift+mouse-click behaviour (select range)
• Extends this behaviour to the keyboard (try capital X)
• Checkbox state is not persisted (feature)
• The scroll into view behavious is also a bit different, and works also in Safari.
• A flexible select function is provided
• Oh yes, the chevron is positioned static, also unlike gmail, so you don't have resizing/flow problems.

Usage

 
function Checkbox_OnToggle(chk) {
  chk.parentNode.style.background=chk.checked?'yellow':'';

  if(String.fromCharCode(e.charCode||e.keyCode)=="o") 
    alert("Opening "+chk.value);
