The instructions for Mountain Lion and other OSs do not seem to apply to Mavericks.
While it may not work in all applications there is a way of doing this for a large number. Certainly it works in
TextEdit but not Microsoft Word, where you have to do it within the application.
All you need to do is open
System Preferences >
Shortcuts and select
App Shortcuts in the left hand pane. Click on
All Applications in the right hand pane and the
+ at the bottom.
Menu Title field enter
Paste and Match Style then click in the
Keyboard Shortcut field and press command-V. Then click on
You will now see that your shortcut is added. When you open
Pages, for example, you will see that
Paste no longer has a shortcut (you could add one using the same method) and right next to
Paste and Match Style in the
Edit menu is your new working shortcut,command-V. Oh, frabjous joy!
I use the following command to maximize the current window in macOS Mojave (10.14):
defaults write -globalDomain NSUserKeyEquivalents -dict-add "Zoom" "@\$m";
so, I suppose this must work in your case:
defaults write -globalDomain NSUserKeyEquivalents -dict-add "Paste and Match Style" "@\$v";
for other keys use:
Command: @ Control: ^ Option: ~ Shift: $ Tab: \U21e5 (Unicode code point for ⇥ character)
