+Explorer
+========
+
+You can open a read-only explorer widget inside the viewer, from "File" menu or shortcut "Ctrl+Shift+E". From the 
+explorer you can open files by double-clicking them, or filter files with wildcard strings. When a file is copied
+by "Ctrl+C" its absolute path is always copied to the clipboard.
+
+Text File Viewer
+================
+
+When you double-clicked a txt file in the explorer, a read-only text file viewer widget is added to the viewer. You can
+search by words or regular expressions in the widget. This widget is very useful when you want to view an image file and
+refer to its metadata file at the same time.
