For automatic crop, the assigned shortcut key is "Alt+Y", but it doesn't work.
For "Tool"-> "Multipage file" menu, it was assigned with "Shift+A". But it looks like a mistake as it has submenu. Moreover, "Create strip of images" has already been assigned with "Shift+A"
"Tool"-> "Multipage file" - "Shift+A" shortcut has been removed - fixed (in RC1), but the correct shortcut is still missing for Tools > Multipage file > "Create" (Shift+M) - this shortcut is working, it's just missing in the menu.
