Yes, the options dialog:
Tools menu -> Options...
Enter 'alias' in the search field, then press return. Once the list populates, scroll to the bottom and select "Search Results" Once the results list populates, double-click on any of the displayed items. Nothing happens. I tried a sampling of many of the results and none worked.
I tried a different search term - 'complete' and some of the results I tried will go to the page when double-clicked (Auto-complete, Auto-complete options, Auto-completion), others will not (Auto-list compatible values, alias expansion, Auto-list members, Completion choice, Current class, Syntax expansion, Tab cycles through choices).
Oh, and the linux version is Beta5, not Beta4.
