Since I recommended Win32::GuiTest, I should have given equivalent example using that module, too:

C:\usr\local\share>perl -MWin32::GuiTest=":FUNC" -le "my ($chrome) = F
+indWindowLike(0, 'Google Chrome$'); print $chrome; print GetWindowTex
+t($chrome); SetForegroundWindow($chrome);SendKeys('{F5}')"
[download]

That also refreshes the current Chrome window for me.
