<human>: Last summer, I took a job doing maintenance work for a fairly large real estate company. Shortly after taking the job, I found out that I had been accepted back into university to finish my undergraduate business degree. I had previously let my admission lapse while travelling, and had never been able to complete my last 2 courses via correspondence. I told my managers about everything, and they were very accommodating to me. I took one week's vacation to complete a block week course, and worked half days every Monday so I could finish my last course in the afternoons. In December, I finished the last of my coursework and will now finally be graduating with my business degree. 

I've been searching for jobs that will better suit my education, but they're difficult to come by due to the tanking economy and subsequent layoffs in my local area. While applying for jobs, I found a posting from my current company for an entry level office position in finance. This would not be working in the same division of my company, or even from the same building that I am currently.

I'm wondering how I should approach applying for this? There is a job application page on my company's website, where I can mention that I am a current employee on the form. I can also email the HR department and ask to be considered. On top of that, should I let my current managers know about my intentions early on? Should I talk to them about it before applying? Or should I just submit an application and see if it goes anywhere before bringing it up? Any advice or related experiences would be appreciated!

Can you give me a shortened version of the text?
