Show manual on startup | Whether to open the manual when DocFetcher starts up.
Use OR operator as default in queries (instead of AND) | If checked, DocFetcher will treat consecutive words in a query as if they were concatenated with the `OR` operator. Otherwise, the `AND` operator will be used. See the query syntax for more.
Automatically scroll to first match in preview pane | If checked, DocFetcher will automatically scroll to the first match in the preview pane after you click on a file in the result table and the file is loaded into the preview pane.
Hide program in System Tray after opening files | If checked, DocFetcher will automatically hide in the System Tray whenever you double-click a file on the result pane, or open a folder from the `Search Scope` area.
When closing program window, hide in System Tray instead of exiting | If checked, DocFetcher will be minimized into the System Tray instead of being closed if you click on the close button of the main program window.
Clear search history on exit | If checked, DocFetcher will wipe out its history of entered queries on exit.
Highlight color | The color to use for higlighting matches in the text preview.
Preview font (normal) | The font to use in the text preview; applies to all document formats except plain text files.
Preview font (fixed width) | The font to use for the text preview; applies only to plain text files. You are not required to pick a fixed-width font here, although it's usually a sensible choice.
Global hotkey | The keyboard shortcut specified here can be used to move the DocFetcher window to the top after it has lost focus.
