The solution is to use Keyboard Shortcuts to switch the Edit menu's items for Paste and Paste and Match Style. It's such a simple fix, I never thought to do it before now. After this fix, Command+V will paste and match style and Command+Option+Shift+V will paste (and keep the style the copied text was in).
- Open System Preferences
- Click Keyboard
- Click the Shortcuts tab
- Click the "+" button
- Select TextEdit
- For Menu Title, enter exactly: Paste
- For keyboard shortcut, type a Command+V
- Click Add
- Click the "+" button
- Select TextEdit
- For Menu Title, enter exactly: Paste and Match Style
- For keyboard shortcut, type a Command+Option+Shift+V
- Click Add
[crarko adds: Simple, but useful. This kind of thing is applicable to pretty much any application. Do most folks here look into customizing their UI to suit their own work habits? For me editing this site depends heavily on customizations in (and around) BBEdit.]
