Key controled Dialog

[rancidrat]

Hi
I am working on a game that only works with the keybored, so i am going to disable the mouse completely. I was wondering if there is a way that I could control dialog options with the keybored for example if you want to choose dialog option1 you can press 1 or maybe even have it scroll between options when you press the arrow keys. Is this at all possible and how would I do it?
Do i need a plugin for it?

Number dialog options - adds an index number before each dialog option when they are displayed to the player. For example,
1. Hello there!
2. Goodbye

This allows you to visually show the player which option the shortcut keys will choose, as well as seperating the options if you don't use a bullet point.
