I often use o ne note, more in modern UI but I can't find a way to select text for copy and past
I would like to do it with pen but I can't select with finger neither
1. Press and hold button 2 (the upper button nearest the clip). This allows you to make a selection using a lasso.
2. Make your selection. When you're done release the button. An "A" will appear, tap that and a circular menu will pop up.
3. Select copy.
4. Switch to the app you want to paste into and press Ctrl + V. If you want to paste into OneNote, using your finger tap where you want to paste and either press Ctrl + V or tap the "paper" icon and another circular menu will pop up and allow you to paste.
