Mail: Decrease quote level does not work as keyboard shortcut
command-option-apostrophe does not work in Apple Mail for me (Mail 7.3, OS 10.9.3). This is the keyboard shortcut used to decrease the quote level of a quoted line in a Mail message. In other words this is the keyboard shortcut for the menu item:
Format --> Quote Level --> Decrease
It hasn't worked for me since at least 10.8. Are others having this problem or do I need to dig more deeply through system extensions, looking for some kin of conflict?
