title: How to browse through the full command history in RStudio
body: <p>Occasionally I had not saved my source script, and its old version opened. I can find the new version which was executed during the previous session, but only like shreds: I search in history and it shows me a piece of code, but not all lines though they were executed simultaneously. Is there any way to access the complete history, which is definitely stored somewhere, but not shown as a whole? Thanks!</p>
  
  <p>I am using R version 3.6.2 and RStudio Version 1.2.5033.</p>
