New buttons: Paste button and Undo button.
Having a 'Paste' button and an 'Undo' button would be very extremely useful when composing messages, especially when i hit the wrong button and everything i just typed or attached disappears and i have to start all over again. Yes, it happens more often than you may think. thank you so very much!

FYI - I utilize a Windows computer. If you do also, the following shortcuts should work for your issue. Hold the CTRL key down and click the letter Z to "Undo" your previous items. So if you accidently delete a section or all of your email that you were typing, click CTRL Z and it will undo the deletion that you just did.
If you want to paste data into an AOL email, you can use CTRL (holding it down) and the letter V to do the pasting.
You didn't ask but there are two other common shortcuts that work with AOL mail on my Windows computer. CTRL X to cut data and CTRL C to copy data. The cut command will erase whatever you have selected (highlighted) and it is now in your clipboard for you to paste it somewhere else. The copy command will copy what you selected without erasing it.
Good luck, I hope this helps.
