Situation: more information about some entries is something thought.

Experienced: entries offer "Copy to clipboard".

Expected: directly launching a Google (or other, customizable!) search engine on the selected filename/entry.

Actually, there's already an undocumented feature allowing that; just create a file named RunAlyzer.Searches.ini in the application folder and fill it with the following contents:
[Startup]
Altavista=http://www.altavista.com/web/results?q=%TERM%
Google=http://www.google.com/search?q=%TERM%
Yahoo=http://search.yahoo.com/search?p=%TERM%
SysInfo.org=http://sysinfo.org/startuplist.php?filter=%TERM%

[CLSID]
Altavista=http://www.altavista.com/web/results?q=%TERM%
Google=http://www.google.com/search?q=%TERM%
Yahoo=http://search.yahoo.com/search?p=%TERM%
SysInfo.org=http://sysinfo.org/bholist.php?filter=%TERM%
I'll expand 0.7.4 to allow the pattern %FILENAME% in addition to the existing %TERM%.

PS: Please feel free to recommend more useful lookup sites :)
