Vim Visual mode

Cut and paste:

Position the cursor where you want to begin cutting.
Press v (or upper case V if you want to cut whole lines).
Move the cursor to the end of what you want to cut.
Press d to cut or y to copy.
Move to where you would like to paste.
Press P to paste before the cursor, or p to paste after.
Copy and paste can be performed with the same steps, only pressing y instead of d in step 4.

The name of the mark used is related to the operation (d:delete or y:yank).

I found that those mark names requires minimal movement of my finger.
