When searching keyword terms in developers toolkit, the results sometimes run off the side of the page (like when there's a long line of code in the results). This can be fixed as follows:

Edit file /admin/includes/stylesheet.css
Change line 35:
td.main {padding: 5px 2px;}
To this:
td.main {
  padding: 5px 2px;
  word-wrap: break-word;
  max-width: 800px;
