When using the character keys to take you do file name
example
pressing 'd' will take the file explorer to the files starting with D
a little find box appears at the bottom of the lister.
if you use this short cut to take you to the last or 2nd last file in the directory (also if there is enough files in the directory that there is a scroll bar/ and using it in detail list form(have no tested other listing styles)
when the find file is highlighted, then you use the mouse to click on it, the find bar will disapaer, and you have then selected the 3rd last file.
