 This plugin works by triggering custom behavior when certain [zle widgets](http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html#Zle-Widgets) are invoked. You can add and remove widgets from these arrays to change the behavior of this plugin:
 
 - `ZSH_AUTOSUGGEST_CLEAR_WIDGETS`: Widgets in this array will clear the suggestion when invoked.
-- `ZSH_AUTOSUGGEST_MODIFY_WIDGETS`: Widgets in this array will modify the buffer and fetch a new suggestion when invoked.
 - `ZSH_AUTOSUGGEST_ACCEPT_WIDGETS`: Widgets in this array will accept the suggestion when invoked.
 - `ZSH_AUTOSUGGEST_PARTIAL_ACCEPT_WIDGETS`: Widgets in this array will partially accept the suggestion when invoked.
 
+Widgets not in any of these lists will update the suggestion when invoked.
+
 **Note:** A widget shouldn't belong to more than one of the above arrays.

 ### [`zsh-history-substring-search`](https://github.com/zsh-users/zsh-history-substring-search)
 
-When the buffer is empty and one of the `history-substring-search-up/down` widgets is invoked, it will call the `up/down-line-or-history` widget. If the `up/down-line-or-history` widgets are in `ZSH_AUTOSUGGEST_CLEAR_WIDGETS` (the list of widgets that clear the suggestion), this can create an infinite recursion, crashing the shell session.
+The `history-substring-search-up` and `history-substring-search-down` widgets are not bound by default. You'll probably want to add them to `ZSH_AUTOSUGGEST_CLEAR_WIDGETS` so that the suggestion will be cleared when you start searching through history:
-
-For best results, you'll want to remove `up-line-or-history` and `down-line-or-history` from `ZSH_AUTOSUGGEST_CLEAR_WIDGETS`:
-
-```
-# Remove *-line-or-history widgets from list of widgets that clear the autosuggestion to avoid conflict with history-substring-search-* widgets
-ZSH_AUTOSUGGEST_CLEAR_WIDGETS=("${(@)ZSH_AUTOSUGGEST_CLEAR_WIDGETS:#(up|down)-line-or-history}")

-Additionally, the `history-substring-search-up` and `history-substring-search-down` widgets are not bound by default. You'll probably want to add them to `ZSH_AUTOSUGGEST_CLEAR_WIDGETS` so that the suggestion will be cleared when you start searching through history:
 
 ```sh
 # Add history-substring-search-* widgets to list of widgets that clear the autosuggestion
