How do I capture keystrokes on the web?

Question

Using PHP, JS, or HTML (or something similar) how would I capture keystokes? Such as if the user presses ctrl+f or maybe even just f, a certain function will happen. ++++++++++++++++++++++++EDIT+++++++++++++++++++ Ok, so is this correct, because I can't get it to work. And I apologize for my n00bness is this is an easy question, new to jQuery and still learning more and more about JS. ```

Accepted Answer

Sure, the only way to do this would be through JavaScript, and you'd do so like this:

```
window.onload = function() {
   document.getElementsByTagName('body')[0].onkeyup = function(e) { 
      var ev = e || event;
      if(ev.keyCode == 70) {//&& ev.ctrlKey) {
         //do something...
      }
   }
};
```
