How to call a JavaScript function using keyboard shortcut?
Question
There is a website which consists of main frame and some additional ones (they're responsible for parsing inserted data). When I start to edit a record, new frame appears. In the source code I see some JavaScript scripts added. Some of them come from site directories, but also there are some defined in the <head> section of the frame. And there is a function defined, let's call it parseData(input){...} , which is then called upon pressing "Save" link.
Is there any way to assign a keyboard shortcut to execute saving? There are no ids defined for the "Save" link, only href and class .
I tried bookmarklets*, but was stuck on joining the frame URL and the JS function call. Any other ideas?
Edit: * bookmarklets are meant to be launched using Shortcut Manager-like web browser extension.
Edit2: I'm not developing the website. I have read-only access to it.

If you want to use pure javascript to bind, say, "enter" to the function parseData, you could use:
document.onkeydown = function(e){
e = e || window.event;
keycode = e.which || e.keyCode;
if(keycode == 13){ // '13' is the keycode for "enter"
e.preventDefault();
parseData(input);
}
}

You might want to use jQuery with this plugin to create keyboard shortcuts. Have a look at this:
You may do something like this:
$(document).on('keydown', null, 'ctrl+s', saveFunction);
