Here is another quick Google tip! You can make your own substitutions, which will help a lot during writing. Google docs make a list of auto substitutions, but you can also customize it as you like. To do this: Go to Tools –> Preference –> make a change in your requirement. You’ll notice a list with two columns, Replace and With. The text in Replace is what you type and the text/symbols in With is what will be substituted when the corresponding Replace strand is entered. When you are done click OK.
You can also click to turn off all automatic substitutions by unchecking the Automatic substitutions box, or you can turn off specific substitutions individually by unchecking the box next to that entry.
Hope this helps!
