In 2011, Sharon Vaknin covered how to add a bit ofto your Google+ posts. If you want bold text, surround the text with asterisks *like this*. For italic text, _write it like this_. And for strikethrough -just add these hypens-.
This collection of punctuation for emphasis formatting still works today, but isn't represented on the graphical interface. When you're writing a longer update, you may forget that you wanted to bold or italicize some of the words.
With the Chrome extension Post Editor for Google+, you can quickly format a post without needing to remember any of the punctuation. Instead, emphasis buttons will be added to the posting interface. The end result is a text input box that looks like one you would find on forums, sans the ability to add HTML formatting for links or inline images.
To put these handy emphasis buttons at your disposal, install a copy of Post Editor for Google+. After installing, if you have Google+ open, you'll simply need to re-open it in a new tab -- a browser restart is not necessary.
Start a post on Google+ and you will see the emphasis formatting buttons appear below the text input area. Just highlight text and click the appropriate button to use the formatting. There's also a small selection of symbols to add some character, if you choose.
