Is your feature request related to a problem? Please describe.
When using the pie chart to locate mob spawners, I need to click a lot of buttons or press lots of keys each time I want to increase the render distance by one. Even when I automate this using my macro recorder, I then need almost as many interactions to see the numeric value of the render distance that turned out to be correct.

Describe the solution you'd like
In the key bindings, I can set keys for "Render distance +1" and "Render distance -1".
Even better if I can use a three-key combination rather than a single key. (Others might prefer less or more.)
Iris would then log to ingame chat a message like "Render distance is now 4."

Describe alternatives you've considered
My bash script to send the required keystrokes via xdotool.

Additional context

This was in Vanilla, but then removed for an unknown reason. Iris probably won't readd it.

I see. I'll extend my script then to guess current value by tracking its own invocations. (Edit: Done.)
Does anyone know a mod that adds the hotkeys back?
