Command+A Unable to adjust font(Equal width)

[Hypdncy 0]

I can·t set the default font for all note , and I can·t change font(Equal width) by Command+A  when code in note

The default fonts are preselected and can only be changed for an individual note. There are many threads with workarounds for new notes, either by templates or duplicating notes.

Code block is an object inside of the note, and is treated differently from normal text. I am not sure I correctly understand what you expect when you press cmd-A.
