I want to write some really simple notes to myself about some code I am writing.
Actually, it would be sufficient just to put e.g. [CODE]...[/CODE] brackets round bits of quoted code so that it appears a different colour.
I found a list at What languages does Pluma / Gedit text editor cover for syntax highlighting?
But that is rather daunting. I'm not keen to research all the items listed there.
Can anyone recommend a very simple option that would do what I want?
