Adding [escape] to NPC dialogue main menu

As the title implies, a general request to add [Esc] as a function in the main NPC menu. Thus far, I’ve likely hit escape nigh every time when trying to close out of the NPC menu, but the only key tied to closing the branching menu is [r].

For the love of the most minute and rather unimportant convenience, the request is to function in the escape key to exit the NPC menu when talking to an NPC.

I too have done the same many times, it would be even more convenient when playing on my phone
