Another surprising and very special feature inside TextEdit, copying style. It can copy definitely all styles, those styles are :

1. Underlines
2. Strokes
3. Text Color
4. Font Shadows
5. Font Family
6. Font Weight
7. Font Size

It is like usual copy-paste action with a little tweak as the purpose is to copy the invisible part, not the visible one. Usual copy is C and paste is V, in this copying the invisible case C and pasting with V. It's only needed an addition .

Additional styles like Kern, Ligature, Baseline, and Character Shape also count as styles.

No more repetitive adjust style tasks, no more grumbling; Thanks to TextEdit.
