Correct terminology?

Im lost and dont know what words to google.

Im trying to script going to a webpage and login then click on link and then put data in a field and then click search save results. Anyone have the correct words or phrasing to get the decent results on google or here.

I think using python module selenium is a start but i have no idea based on the stuff ive read i think it just reads/searches for words on a web page. Curl/wget ? but i dont think it can login ? lost completely ?
