#### Common regex use cases
- to list all matches starting with the filter expression, start with a `^` (caret)
- type `\.mkv` to list all MKV files
- use `.*` to match any character (_sort of_ fuzzy search)
- exclude filenames having `nnn` ([with PCRE](https://github.com/jarun/nnn/wiki/Developer-guides#compile-with-pcre)): `^(?!nnn)`
#### Limitation
Use regex for case-sensitive filtering with wide chars as the function [`strcasestr`](https://manpages.ubuntu.com/manpages/bionic/en/man3/strcasestr.3.html) (used for string filters) does not work with multibyte locales ([ref1](https://www.gnu.org/software/libunistring/manual/libunistring.html#char-_002a-strings), [ref2](https://www.gnu.org/software/gnulib/manual/html_node/c_002dstrcasestr.html)).
## Type-to-nav
In this mode directories are opened in filter mode, allowing continuous navigation.
To start in _type-to-nav_ mode, use the program option `-n` or press <kbd>^N</kbd>.
