title: A script for google spreadsheet to provide multiple hyperlink choice for one cell
body: <p>I have a google spreadsheet.  In some cells, it has multiple names(strings) that I would like to associate with individual hyperlinks.  </p>
  
  <p>E.g. if I have a cell such as "Charles Darwin", it's easy for me to create a hyperlink out of this name by doing something like 
  <code>
  =Hyperlink(VLOOKUP("Charles Darwin", People!$A$1:$B$738, 2, false), "Charles Darwin")</code>
  (note that I have a "People" sheet from which I grab the hyperlink)</p>
  
  <p>But if I happen to have multiple entries in that cell, say ";" or newline separated, e.g., "Charles Darwin; George Washington", I can't do that.  I'd like to give the user an ability to click on the cell, have the contents of the cell be sent (as argument) to some kind of script, and for that script to find the hyperlinks in my "People" sheet for those strings, and then to present the user with a little "pop-up" right next to that cell, where the desired hyperlink could be clicked on.</p>
  
  <p>I tried to find something along those lines on this site, but nothing similar seemed to come up.  Might someone have a link or two for me (or basic example code) that I could start with to try to solve this? (I am assuming this is possible).</p>
