Copy-paste words from MUD text
It would be cool if you could have a button to tap next to the text input box that when pressed allows you to select any word or string of words from the text on the screen, and automatically pastes it into the input box.
This would make interaction with long-spelled objects a lot easier, since you could just type "look at" then select the word/string and then press send.
I think it would be better if you limit the selection to only whole words too (not being able to select only half of a word, or a few letters of a word)... I don't see too many instances where you wouldn't want to select the whole word...
