Google Plus Tricks I place this ‘cheat sheet’ here, where I need it.
• Simple text formatting
bold: * bold * (drop the spaces after/before asterisk)
italic: _ italic _ (drop spaces)
strike through: - strike through - (drop spaces)
• Tagging people on posts
add ‘+’ or ‘@’ symbol in front of their name
• Sending a private message
just share with that person
• Keyboard shortcuts
space / space-shift: scroll down/up stream
j / k: single post down/up scroll
Those are the ones I know & use. Mostly learned from iGuru.
