No, the html file itself. It just contains elements like a paragraph, image, list, table,… just like a word document.

A word document can also contain a script, as can html pages. It’s why I thought these two were the closest match. Nobody is going to call those programming languages.

A PowerPoint, word document or even a text file or picture. There is only a description in the file of what it holds and it’s up to the program that reads it, how it will visualize or interpret it.

A word document or PDF would be the closest.

I use it to open the spell checker options while I’m typing. It’s annoying to have to switch from keyboard to mouse. My current laptop doesn’t have the key and I even added another short key.

The super key, again, is useful so you don’t have to switch between keyboard and mouse when searching for an app. It is also the modifier for all GUI shortcuts.
