Cheymus

I am new to Ubuntu. I am trying to download the java applet that enables the streaming quotes in Scottrade. I found the appropriate code online and entered it in the terminal. The program downloaded and after several minutes I was presented with an agreement. The problem is I do not know how to indicate my acceptance. There are a series of <Ok>'s after each few paragraphs. Clicking them with the cursor does nothing. It does not seem to be possible to ad any further script. In any case I could not find any command which says "OK, I accept the agreement"
The answer to this is probably laughably simple, but at this point I am completely stumped
