Ever wonder what happens to all those links and other things you have copied to your clipboard before pasting in a post or document? Long press on the microphone key on your Samsung keyboard to find out and delete anything you don't need anymore.
Thanks to members Jeffruby and Klotar in the LG G2 forum
for pointing this out. Not specifically a Note 3 tip but pretty cool nonetheless.
You can also reuse clipboard items by just tapping on them after the microphone key long press. You have to redo url tags though.
