select key doesn't work

Even though i changed [list item selection key] options from [Enter] to [tab], it does not work correctly. It still work with only [enter] key.

You are likely using one of the plugins, but instead of changing local options in the plugin, you have changed global options after which you didn't restart all target editors. Either change SQL Assistant options locally using Options in the context menu in the editor or restart the target. Hope this helps.
