One of my favorite keyboard shortcuts is Command and F. This shortcut will bring up a search box right under the omnibox, and will search the current page you are on to find the term you specify.
I use this feature all the time on our CUSD Vetted Apps and Website Spreadsheet to find out what category a certain tool falls into. Check out this short video on how I searched our spreadsheet for the tool Kahoot.
Great news, is this is available on your iPad too! If you want to search a specific term on a website (take our blog for example) head up to the omnibox in your iPad, and begin typing the terms you are searching for. You will see a variety of options such as Wikipedia, Google Search, and On This Page. Select “On This Page” and that terms will be highlighted for you!
