Install the package `xdg-utils`, then make very liberal use of the tab button.
## Ask
Ask what type of application opens an mkv file:
```bash
xdg-mime query default video/mkv
```
Same with pdf:
```bash
xdg-mime query default application/pdf
```
Ask what file-type `book.pdf` uses.
```bash
xdg-mime query filetype *book.pdf*
```
## Set
Set the mime type of mp4 videos to mpv.
```bash
xdg-mime default mpv.desktop video/mp4
```
You'll need to use the tab key a lot here, and remember many items start with `org`.
You can use an asterisk for everything in a category.
```bash
xdg-mime default org.gnome.font-viewer.desktop font/\*
```
This often won't work as expected, because some fonts will have the type `application` rather than `font`.
