How can i look up where Constants are defined using Aptana
<p>I am currently working on a shopping cart using an open source PHP framework. it is quite large. i recently installed a plugin that included over 160 separate files!, there is now some kind of logic error going on.</p>

<p>My question is, in using Aptana Studio how i can do the following?</p>

<p>find where a constant is being defined?
find where a function is defined?
is there any way to track variables?</p>

<p>thanks for any help or advice on this</p>
