Function key bar
By pressing one of these buttons or by pressing one of the Function keys F1 to F8 you can activate the corresponding function. For the functions Help (F1) and Reread directory (F2) there are no buttons to avoid overcrowding the window. The F3, F4 and F8 buttons also work as targets for Drag&Drop.
In the 32-bit version, you can right click on the F8 button to open the Recycle Bin.
