How to draw arrows in Photoshop CC:
1. First open photoshop CC and create a new 500px X 500px document.
2. Find the “Rectangle Tool” in the toolbar, as shown in the picture.
3. Right-click it with the mouse, or long-click it with the left button, and a drop-down menu will appear. Find the "Straight Line Tool" in the drop-down menu, and click it to select the "Straight Line Tool".
At this time, this place in the toolbar is switched to "straight line work".
4. Then find the button as shown in the picture in the property bar and click it.
5. At this time, the "Arrow" menu will pop up. Check the box in front of the end point. Don't worry about other things. The default will be fine.
If you want to have arrows at both ends, just check the starting point as well.
6. Return to the newly created canvas, hold down the mouse, and drag it, an arrow will appear.
