When typing a path into the location bar, the tab key completes the path you are typing in. When more than one completion is possible, pressing the tab key does nothing, for a second anyways. When the list of possible completions appears, pressing the tab key (as someone would do if they are in a hurry) instead follows the standard behavior of shifting focus among widgets within a window. Reproducible: Always Steps to Reproduce: 1. Activate the "toolbar style" location selector 2. Select the path entry and begin typing 3. When "popup" showing possible completions appears, press the tab key Actual Results: Focus shifts from the location entry to the bookmarks pane. Expected Results: Make the tab key have no effect, if possible. Keep the list of possible completions active and shown. Thunar 0.2.1svn-r19838
Bug #1346 already covers/covered that problem. In short: There's nothing one can do about it from outside Gtk once the completion appears, this has to be handled in Gtk+ (you can file a feature request to gnome bugzilla, dunno if it will be accepted). The only thing we can do about this is to disable the completion box, which will only work with Gtk 2.9/2.10, as my patch wasn't applied to 2.8. *** This bug has been marked as a duplicate of 1346 ***
Odd that the bugzilla searches didn't turn that one up. Sorry for the duplicate.
Maybe you didn't look for closed bugs?
