Compact schedule in agenda day view

[Angel de Vicente]

Hello,

I was too quick on the keyboard and I pressed some magic key combination
and now my schedule for today shows in a compact way (only showing the
appointments). I actually prefer the "expanded" way, in which I get a
grid for the whole day (so it easier for me to quickly see if an
appointment is in the morning or the afternoon, etc.).

The problem: I don't know how to go back, and I'm not sure how this
feature is called, so I was not successful searching for it in the
manual.

Anybody knows off the top of your head how to toggle this?

Many thanks,
