Sorry, I am not sure if this is a right place to suggest a minor complement to the Pollen documentation, but I didn’t find any accessible issue tracker for this.
I only plan to try Pollen, and I was thinking which editor to use, and if I should use lozenges or configure another command character, like @.
I’ve almost missed out yet another way to get lozenges in my editor (Vim) because it is not mentioned in Pollen documentation: I can use snippets! For example, I can define a snippet such that typing @<Tab> will produce ◊.
So, I think it is worth mentioning in the docs that snippets or other configurable auto-completion facility or plugin can be used to get characters not available on the keyboard.
