+`wd` comes with an `fzf`-powered browse feature to fuzzy search through all your warp points. It's available through the `wd browse` command. For quick access you can set up an alias or keybind in your `.zshrc`:
 
 ```zsh
-bindkey ${FZF_WD_BINDKEY:-'^B'} fuzzy_wd_widget
+# ctrl-b to open the fzf browser
+bindkey ${FZF_WD_BINDKEY:-'^B'} wd_browse_widget
