• "fop" matches "file: open file"

If option is off, filter uses normal search. "Normal" means that filter leaves only those listbox items, which contain all words from the filter (in any order).

Filter field can find hotkeys too. Enter only hotkey substring, with first "@" char. E.g. "@ho" finds "Ctrl+Home". This search is not fuzzy.

• p - plugins

• l - lexers

• r - recently used files

You can type those "hash tags" at begin or end of the field, even without separating space. E.g. "bar#p" will show only plugin commands containing "bar", "#f.md" will show only Markdown files.
