  description

  When you access a web page, this extension extracts a sequence of four or more consecutive digits (such as a stock code or zip code) from the current page URL.
  
  You can select a jump destination with the digits from the right-click menu.
  You can also rate the digits as good, neutral, or bad, and save the rating.
  You can keep a memo for each digit, and there is a button to easily append the current tab’s title to your memo.
  
  For example, if you are searching for rental properties in Mountain View on Zillow and visit
      https://www.zillow.com/homes/for_rent/94041_rb/
  using this extension, the number "94041" (the zip code) will be extracted.
  
  You can then jump to the search results for nearby Bank of America branches or ATMs:
      https://locators.bankofamerica.com/?q=94041
  
  If you like Mountain View, you can rate the digits - "94041" as good and keep it in your Chrome.
  
  I live in Japan and created this extension to jump from Yahoo Finance Japan’s page
      https://finance.yahoo.co.jp/quote/7974.T
  to Minkabu’s page
      https://minkabu.jp/stock/7974
  and save ratings of stocks.
  
  The extracted number will be added to the end of the specified URL in the settings screen.
  If you want to insert the extracted number in the middle of the URL, you can use %s in the URL, and the number will be placed there.
      Example: https://finance.yahoo.co.jp/quote/%s.T
  
  Your ratings and memos are stored per number and can be deleted at any time.
  The 10 most recent ratings are displayed as a list, and you can quickly jump to the corresponding URLs from the list.
  You can also view all your rating history in a separate screen.
  
  This extension is free, but there is a “Buy me a coffee” link in the settings screen.

  Numdex (formerly "Page Jumper") extracts numeric codes — such as stock codes or zip codes — from the URL of the page you are visiting, and helps you jump to related pages, rate each code, and keep notes.
  
    How it works
    - Extracts numeric codes from the current URL, or from text you have selected on the page. The numeric range can be customized in the settings (default: positive integers of 4 or more digits).
    - Jump to your chosen destination URLs from the popup or the right-click context menu.
    - Rate each code as good, neutral, or bad, and save a memo. A one-click button appends the current page title to the memo.
    - The popup shows the 10 most recent ratings. A separate "All Ratings" page lets you filter, sort, edit, import, and export your saved data.
  
    Examples
  
    If you are searching for rental properties in Mountain View on Zillow and open
        https://www.zillow.com/homes/for_rent/94041_rb/
    Numdex extracts "94041" (the zip code). You can then jump to nearby Bank of America branches:
        https://locators.bankofamerica.com/?q=94041
    If you like the area, rate "94041" as good and your Chrome remembers it.
  
    (I live in Japan and originally built this to jump from Yahoo Finance Japan
        https://finance.yahoo.co.jp/quote/7974.T
    to Minkabu
        https://minkabu.jp/stock/7974
    and save my impressions of stocks.)
  
    Destination URLs
  
    Configure your destinations in the settings screen. The extracted code is appended to the end of the URL by default, or you can place it inline using %s:
        Example: https://finance.yahoo.co.jp/quote/%s.T
  
    Other features
    - An on-page rating indicator (a floating badge) on sites you enable in the settings.
    - JSON import/export for ratings, with an option to also include destination URLs, enabled sites, extraction range, and language.
    - UI available in English, Japanese, Spanish, Simplified Chinese, Traditional Chinese, and Korean.
  
    This extension is free. A "Buy me a coffee" link is available in the settings screen.
