My first gripe is about how finder responds to the Option + left arrow and Option + right arrow keys when renaming files. It appears to have been designed by a drunken lobster. Hitting Option + left or right arrow while playing with a filename that contains text, numbers, periods and dashes is a fun exercise. The system treats periods, dashes and other characters as separators, but there's no telling whether hitting Option + arrow will land your cursor before or after the separator, or even skip the separator altogether and jump to the next word. My second gripe is about how you can use the keyboard instead of the mouse to activate some but not all buttons in the OS. For example, Shift + Option + Backspace in finder lets you clear the trash. It pops up a window asking you to confirm, and you hit enter and off it goes. Now try renaming a bunch of files in finder. You can't even use TAB to navigate to the RENAME option to select it. Nooo... you must use the clicky thing.
