Ever wanted to keep your hands on the keyboard and navigate your tabs in Google Chrome? Well, I try to keep my hands on the keyboard as much as possible, so I took to Google to search for this, and wallah, it led me to this info:

To switch to the next tab: Ctrl+Tab or Ctrl+PgDown To switch to the previous tab: Ctrl+Shift+Tab or Ctrl+PgUp To switch to a specific tab: Ctrl+1 to Ctrl+8 To switch to the last tab: Ctrl+9
