While creating a template sensor, the code window is sometimes too small to understand what is happening. Specially when you have long entities names (which sometimes is the only way to differentiate between a lot of similar devices).
If we want to put some indentation, it will not be correctly applied.
Double tap on the white space between Template binary Sensor and the question mark and the screen will enlarge to the size of your browser window.
Double or single?
it’s one of the two 
EDIT: Would ya look at that, it looks like it’s not available on that window.
Are you sure about it? I could never get it to work in that window.
It’s not working, I just went to find out for Tom. It must not be available outside dashboards. WTH
It would appear this is the case for all helper config flow cards.
