You know you can go to your settings and activate ‘Prefer Markdown input where available’.
Then you will be able to use the triple back-ticks (```) to enclose codes, tracebacks, errors, etc.
Like:
```
SCRIPT ERROR: Invalid get index 'L59L1 21' (on base: 'Dictionary').
at: update (res://gui_modules/Exploration/Scripts/room.gd:24) - Invalid get index 'L59L1 21' (on base: 'Dictionary').
SCRIPT ERROR: Invalid get index 'L59L1 22' (on base: 'Dictionary').
at: update (res://gui_modules/Exploration/Scripts/room.gd:24) - Invalid get index 'L59L1 22' (on base: 'Dictionary').
```
That will give :
SCRIPT ERROR: Invalid get index 'L59L1 21' (on base: 'Dictionary').
at: update (res://gui_modules/Exploration/Scripts/room.gd:24) - Invalid get index 'L59L1 21' (on base: 'Dictionary').
SCRIPT ERROR: Invalid get index 'L59L1 22' (on base: 'Dictionary').
at: update (res://gui_modules/Exploration/Scripts/room.gd:24) - Invalid get index 'L59L1 22' (on base: 'Dictionary').
Isn’t that better to read?
Edit :
Or you can also click ‘¶’ (that is the Format button) then ‘Code’ when not using Markdown.
