Paste and Match Style - Default?
This will do the trick:


Go to System Preferences / Keyboard / Keyboard Shortcuts / Applications.
Click the + button.
Choose All Applications, from the drop-down list.
On the menu title field add the exact name of the menu bar item.
Pick your keyboard shortcut and click Add.




In case you overwrite the default Command+V shortcut, if the application lacks the Paste and Match Style option, paste will work as usual.
