Kuickshow used to have a function to delete the currently viewed picture in its 
viewer window. This is very useful for sorting out digi-photos: Look through them 
with PgDn and PgUp and get rid of bad photos (unsharp, people walking through the 
main motive, whatever) with one key press: Hit the "Delete" key and after a 
confirmation popup the image was gone. 
 
The Kuickshow we ship with 10.0 lost this function: Nothing happens when you hit 
the "Delete" key in the viewer window. There is also no item "Delete picture" in 
the context menu. "Shift-Delete" (the shortcut for "delete picture" in the browser 
window) also does nothing. 
 
After some investigation it turns out that there is a way to restore that 
behaviour, even though it is awkward and most likely depends on another bug: 
 
There is no action "delete picture" in the "viewer shortcuts" tab of the 
"settings" dialog, but if you change the "delete picture" in the "browser 
shortcuts" tab from "Shift-Delete" to "Delete" and confirm the warning that the 
"Delete" key is assigned to the global "move to trash" action, "Delete" again 
deletes the current picture even in the viewer window (after a confirmation 
popup, of course). There is still no "delete picture" item in the viewer's 
context menu, though.
