About eclipse 2.7 commands.

I got a question:

Is there something like if player click here then something happen?

How I do message text boxes? For example:

I go to a Npc, and talk to it.
A window appears with the name of the Npc, a text like "Hello do you need something?" And options like "Yes, who are you?" and "Nah, bye" and if select the first option the text changes and… Well you understand.
