Make friends with the Shift key.
When dealing with bullet points, the Shift key will save you a lot of frustration. Here are 2 important tips when using bullet points:
Shift + Tab
Hold down Shift while pressing Tab to move a bullet back to the left.
Shift + Enter
As you type a list with bullets, hold down the Shift key while pressing Enter to go to the next line without a bullet. Then, press Enter (without Shift) to continue with the bullets.
