Rhino version 8.10.24226.13001
In the legacy Python Script Editor, I am able to resize the text in the editor AND in the help panel by using Ctrl+MiddleMouseWheel.
In the new Script Editor, Ctrl+MiddleMouseWheel works in the Terminal but not in the text editor and Help windows. Ctrl+MinusKey works in the editor BUT Ctrl+PlusKey does not.
