As I was trying to save my notebook by hitting ctrl + s
, I might have hit a different letter by accident and something unexpected happened:
An extra row appeared below the menus at the top:
and the check-mark seems to now permanently be set in:
Window -> Toolbar -> Formatting
(I tried clicking on it several times, but this check-mark never goes away.)
Worst of all, when creating a new cell, the cell now defaults to a Text cell instead of an input cell.
What happened here? Is there some way to revert my notebook to its original standard behavior?
EDIT:
Following suggestions in the answers, the EditBar is now gone, but all my calculation cells are still indented inward, while text cells are not indented, and creating a new cell also still defaults to a text cell instead of input. Any idea how to fix that?
Also, In: and Out: labels at the left are now grey and turn orange upon evaluation for some reason. This color scheme was not present before...
