 ### Listing, for fzf and pickers
 
 `lazysecrets list` prints every source, vault and secret, one per line:
-its name (`platform-prod / kv-app-prod / db-password`), then its link,
+its kind (`source`, `vault`, `secret`, `key` or `certificate`), its name
+(`platform-prod / kv-app-prod / db-password`) and its link,
 tab-separated. It's what Go to searches, so fzf, or an editor's picker,
 can search it instead, showing the names and acting on the links:
 
 ```sh
-lazysecrets list | fzf --ansi --with-nth='..-2' --accept-nth=-1 \
+lazysecrets list | fzf --ansi --with-nth='2..-2' --accept-nth=-1 \
   --bind 'ctrl-o:become(lazysecrets open {-1})' \
   --bind 'ctrl-y:execute-silent(lazysecrets get {-1} | pbcopy)'
 ```
 
-`--with-nth='..-2'` shows and searches the names, leaving out the link,
+`--with-nth='2..-2'` shows and searches the names, leaving out the kind,
-the last field; `{-1}` and `--accept-nth=-1` are the link. `enter` prints
+the first field, and the link, the last; `{-1}` and `--accept-nth=-1` are
+the link. The kind is one word and the link has no spaces, so this works
+without `--delimiter`. To filter by kind yourself: `awk -F'\t' '$1 == "secret"'`. `enter` prints
 it (`lazysecrets get $(…)`), `ctrl-o` opens it in lazysecrets and `ctrl-y`
 copies the value (`pbcopy` on macOS; `wl-copy` or `xclip` on Linux). A
 value copied this way isn't cleared from the clipboard after
