+====== FAQ: How to find the code behind a given menu command? ======
+You can look in the IJ_Props.txt file the exact plugin called by a given menu command.
+For example for the 'Make Binary' menu entry, the IJ_Props.txt file reads
+  binary01="Make Binary",ij.plugin.Thresholder
+You'll find a copy of the IJ_Props.txt file in your ''ij.jar'' file or at http://rsb.info.nih.gov/ij/download/IJ_Props.txt
+Then visit the source code page at http://rsb.info.nih.gov/ij/developer/source/index.html
+and go to the correct class, in our example the ''ij.plugin.Thresholder'' class.
+Another option to discover which class is called by a given menu item, is to enable the debug mode by checking the 'debug mode' checkbox under ''Edit/Options/Misc...'' dialog, run the investigated function from the menus and read the log output.
+For our example, the debug log reads :
+  actionPerformed: time=1228576256194, java.awt.event.ActionEvent[ACTION_PERFORMED,
+  cmd=Make Binary,when=1228576256194,modifiers=] on menuitem1
+  runPlugin: ij.plugin.Thresholder
+===== "Fiji" case =====
+With "Fiji" ImageJ version, the IJ_Props.txt file don't contain all menu descriptions.
+For example, the menu "Analyze / Directionality" isn't in "IJ_Props.txt" file and the "Debug mode" solution log :
+  actionPerformed: time=12512156, java.awt.event.ActionEvent[ACTION_PERFORMED,
+  cmd=Directionality,when=1339586662984,modifiers=] on menuitem0
+  runPlugin: fiji.analyze.directionality.Directionality_
+This plugin is stored in the following file : "Fiji.app\plugins\Directionality_.jar"
+You can see the link between the plugin and the menu in the text file "Fiji.app\plugins\Directionality_.jar\plugins.config" :
+  # Directionality, builder Jean-Yves Tinevez
+  Analyze, "Directionality", fiji.analyze.directionality.Directionality_
