I use standard fonts like Garamond or Times for explanations, but it's helpful to show the computer program text in a fixed width font.
To show the output from programming languages like Python, I use a fixed width font like Courier New. All goes well until I type a word like 'floor' - it gets a fl ligature instead of the two fixed width characters f followed by l.
I have not found any straightforward ways to type Courier without ligatures.
But, poking around, it appears that using the glyph tool, I may be able to type separate letters (f then l, for example).
Is the glyph tool the only solution?
