If you are in Vim’s insertion mode, which you would recognize by the word “INSERT” down in the left corner of your screen.
And you want to either TAB forward and/or backward but you don’t want to switch to normal/command mode? Well rest assured you can TAB around in insert mode 💡
CTRL + T
Moves you one TAB space forward.
CTRL + B
Moves you one TAB space backward.
Remember, you can always do the cliccie for a larger piccie 😛
