Text in Shortcut Keys Pref Tab

[ahoward]

The Quick Copy feature is referred to differently in different preference tabs. In Export, it is expressly called "Quick Copy", while in Shortcut Keys, the same feature is referenced as "Copy Selected Items to Clipboard". The latter tab should probably refer to it as Quick Copy in some fashion, even if it's just in parentheses after the existing text.

Also in the Shortcut Keys tab, two items aren't capitalized, while the rest are. "Create a new item" and "Create a new note" do not match the others stylistically.
