One recently added feature I found by mistake, is that you can copy and paste in Google Docs, Draw and Presentations. This is really useful and a great time saver. If you see an image online, you can right click, select 'Copy Image', go back to the Doc, Draw or Presentation and Ctrl V or right click and select Paste.If you are making instructions and have taken a screen capture somewhere on your computer (Windows use Snipping Tool, click and drag around what you want to use and choose Copy) Go back to Doc and Paste.
(Macs use Shift -Control -Command-4, click and drag around what you want to use) Now go to your Google Doc or Presentation and Ctrl V or right click and select Paste.
Note: If you are copying from Doc to Doc/Presentation or Draw, you cannot right click, you need to use Ctrl C (Win) Command C (Mac) to copy and Ctrl V (Win) Command V (Mac) to paste.
This process saves you the time of saving images to your computer and then having to go to Insert-Image, choose image, wait for it to load, select image and wait for it to appear on the page.
