If the value is set to a negative value, scrolling is broken as it scrolls to the bad side and never reach the target scroll value until the top or bottom of the script.

Open any long script (you can copy/paste the default template multiples time as it don't have to be valid script)

In Editor Settings, change the value of text_editor/behavior/navigation/v_scroll_speed :

• to a negative value : mouse wheel scroll don't work anymore (scrolls until the top or the bottom of file)
• to a value under 8 : no scroll at all.
