Ability to disable "up arrow key = edit previous message" as well as disable "down arrow key = cancel editing"

[NintendoManiac64]

The Problem

As of v0.12.0 stable, the up arrow key behaves as an "edit previous message" and the down arrow key behaves as a "cancel editing" with no way to disable either functionality.

The Solution

A simple toggle in the settings to disable/enable "up arrow key = edit previous message" as well as disable "down arrow key = cancel editing"

Greater visual indication that you're editing the previous message would also be appreciated (maybe even making the message in question turn into a text box rather than "importing" the text into the "type a message" text box?)

Alternatives

Map a different key and/or key combo to be "edit previous message" that can't be accidentally pressed when typing messages, such as ctrl+e or something. And perhaps, when in the middle of editing, pressing ctrl+e would subsequently cancel editing?

Additional context

I use the arrow keys a lot when typing up longer messages, including the up and down arrow keys.

The up arrow = edit previous message can cause me to accidentally instead edit and overwrite my previous message with minimal visual indication that I'm editing the existing message rather than typing a new message that I've copied-and-pasted.

It also causes the issue of overwriting my currently-typed message with the previous message's contents.

Similarly, when editing a lengthy message, I can end up pressing the down arrow key one too many times resulting in my editing being canceled and losing all modifications I was in the process of making.
