You can easily draw a heart ♥ if you follow the simple instructions.
Steps
Method 1 of 2: Computer with an external keyboard

Step 1. Open a suitable program
Not all Microsoft programs recognize this symbol, but most sites (Facebook or Twitter, for example) understand it.

Step 2. Press the Alt key

Step 3. Press the number 3 on the right side of the keyboard
A heart like this will appear: ♥
Method 2 of 2: Laptop
If you don't have a keyboard on the right, or are using a laptop, you can still achieve this effect.

Step 1. Press the Fn key

Step 2. Hold it at the same time with the alt = "Image" and L keys

Step 3. Some keys on the right hand should be numbered
The heart will appear again. ♥

Step 4. We're done
Advice
- The keys must be pressed simultaneously, otherwise the heart will not pop out.
- Try different combinations of alt = "Image" and other keys, you can get all kinds of results, for example ☺☻ ♥ ♣ ♠ ♥ ☻☺ ♦ ♣ ♠ ○ ◘ •
- Many sites allow you to use the "& hearts;" (no quotes or spaces) to make the heart appear.
- If you don't have an external keyboard, use the Fn key.
- <3 also turns into a heart on Facebook.
