The two ways I can imagine are writing a plugin or modifying DrRacket, and I expect the latter to be easier; my only experience is modifying a DrRacket plugin, and I don't think this is quick, but it's possible. For that, I think you want to look at drracket:get/extend:extend-interactions-text. To be in the context to do that, see http://docs.racket-lang.org/tools/implementing-tools.html and the examples shown there using drracket:get/extend:extend-definitions-text. Below's I'll give an outline anyway of what I actually did, in case it's helpful — though the docs are probably better. == I've been hacking a DrRacket plugin (the handin client), where I use something more complex because I assumed I only had a editor% (so I used insert-port). My call is in https://github.com/racket/handin/pull/27/files#diff-cf0f873382d5f6c351cee18d851376c3R734; the code around it does a number of potentially useful things. The starting point is the call drracket:get/extend:extend-unit-frame, in the context of (define tool@ (unit (import drracket:tool^) (export drracket:tool-exports^) ... drracket:get/extend:extend-unit-frame subclasses the unit-frame DrRacket component, and inside it you can call get-definitions-text and get-interactions-text to get access to the two text%. For that, refer to the docs extensively, starting from http://docs.racket-lang.org/tools/, its index, and the introduction into how to do a plugin. By doing that, I just found out about drracket:get/extend:get-interactions-text, which allows you to subclass the interactions-text directly. While this is a lot, I've found I managed to get something done without needing to understand every detail, also thanks to Racket syntax-check. It's sad it doesn't understand units as well as the rest. (OTOH, I'm scared that I'm writing code without understanding every single line around it. I usually never do that, but I'm new at Racket).
