=Exercise 1 : Using LXR=
I attmeped my search under Mozilla 1.8 and as a text search.
I began my search with 'reload', which returned an overwhelming account of hits.  After s fair bit of reading, I thought I found soemthing relivant in:
/browser/locales/en-US/chrome/browser/browser.dtd
 82 <!ENTITY reloadCmd.label              "Reload">
 83 <!ENTITY reloadCmd.accesskey          "R">
 84 <!ENTITY reloadButton.tooltip         "Reload current page">
which didn't turn out to be much.. so on with my search..<br/>
I decided to try 'reloadCmd', which turned up in my first search, and I found:
 173                 <menuitem label="&reloadCmd.label;" accesskey="&reloadCmd.accesskey;" command="Browser:Reload" key="key_reload"/>
which again, didn't turn out to be much, however taking a hint perhaps I should try, 'BrowserReload', which I got a few hits for, one was in javascript in /browser/base/content/browser.js
 1622 function BrowserReload()
 1623 {
 1624   const reloadFlags = nsIWebNavigation.LOAD_FLAGS_NONE;
 1625   return BrowserReloadWithFlags(reloadFlags);
 1626 }

and in /browser/base/content/browser.js,
 5056       // Reload the page to show the effect instantly
 5057       BrowserReload();

so I'm assuming I'm on the right track..
I then tired 'BrowserReload('.. and found a .cpp file.. I got a little excited (!!) I found it in /embedding/tests/wxEmbed/BrowserFrame.cpp, 
 203 void BrowserFrame::OnBrowserReload(wxCommandEvent & WXUNUSED(event))
 204 {
 205     if (mWebBrowser)
 206     {
 207         nsCOMPtr<nsIWebNavigation> webNav = do_QueryInterface(mWebBrowser);
 208         webNav->Reload(nsIWebNavigation::LOAD_FLAGS_NONE);
 209     }
 210 }
and now I'm at a loss..
