action

Background story: when a user selects a portion of text in a text field with her mouse (mark it up manually), and subsequently hits "alt" key, a certain function would trigger.

My questions are:

How can I trigger a function when a user hits a key (in her keyboard)?
How can I preserve a portion of text selected, and use it as a parameter for that function?

I've tried looking up online but haven't found any good answers, but i'd greatly appreciate links as well.
