If it'd also optionally (default=true) strip text formatting from copy/paste that'd be epic. No more copy-from-browser-then-paste-into-notepad-then-copy-from-notepad-then-paste-into-email-or-chat
After that, almost everything will use cmd-shift-V. However, Microsoft Word is still broken, apparently because it uses a slightly different command that does a similar thing, "Paste and Match Formatting". Haven't found a way to fix that yet.
