Set ZSH_AUTOSUGGEST_STRATEGY to choose the strategy for generating suggestions.
+
There are currently two to choose from:
+
* default: Chooses the most recent match.
+
* match_prev_cmd: Chooses the most recent match whose preceding history item matches
+
the most recently executed command (more info). Note that this strategy won't work as
+
expected with ZSH options that don't preserve the history order such as
+
HIST_IGNORE_ALL_DUPS or HIST_EXPIRE_DUPS_FIRST.
