    66 # Which plugins would you like to load?
    67 # Standard plugins can be found in ~/.oh-my-zsh/plugins/*
    68 # Custom plugins may be added to ~/.oh-my-zsh/custom/plugins/
    69 # Example format: plugins=(rails git textmate ruby lighthouse)
    70 # Add wisely, as too many plugins slow down shell startup.
    71 plugins=(zsh-autosuggestions zsh-completions history-substring-search)
   

2. Find the source code

   $ cd /path/to/oh-my-zsh
   $ grep -rn 'moving the cursor to the end of the result buffer' .
   ./plugins/history-substring-search/history-substring-search.zsh:248:  # existing highlights and moving the cursor to the end of the result buffer
   $ vim -c 'edit +248 ./plugins/history-substring-search/history-substring-search.zsh'

   edit

   247   # the search was successful so display the result properly by clearing away
   248   # existing highlights and moving the cursor to the end of the result buffer
   249   if [[ $_history_substring_search_refresh_display -eq 1 ]]; then
   250     region_highlight=()
   251     # CURSOR=${#BUFFER} # comment out this line!!!
