Hi use the tab key to get to the right hand panel.
Down Arrow key will move your cusor down one folder/files at a time. When the file you want is highlighted, in this case ashsimpl, hit enter
So I guess the answer is the “enter key”
ashsimp2 is the skinless version of the simple user interfacs and ashquick is the explorer extention (right click on demand scanner.)
Ashchest.exe will open the chest.
