From Microsoft, it means:
IntelliSense is the general term for a number of features: List Members, Parameter Info, Quick Info, and Complete Word. These features help you to learn more about the code you are using, keep track of the parameters you are typing, and add calls to properties and methods with only a few keystrokes. Many aspects of IntelliSense are language-specific.
As is clear, the IntelliSense of Cypress Editor is not complete and perfect as for example Visual Studio. It's only the beginning of the road. But I will do my best to improve it :)
When you are writing you code, where you type 2 first chars of a word, the IntelliSense menu will appear and shows you a list of all cantoning words that begin with what you typed and you may choose the word that you plan to write, in correct spell. It's easy as press Enter or Tab key. That's it.
You could scroll up and down in the list.
Every time that you press Ctrl + Space, the IntelliSense menu will appear with all the commands and keywords.

CypressEditor.Editor.Editor Tooltip

If you move mouse pointer over a keyword for a while, a tooltip will appear that contains some help tips about a keyword or command. If the keyword is an OpenSees command, it includes command syntax and arguments.

CypressEditor.Editor.Code Folding

Code folding is a useful option that allows you to collapse/expand a block of code between { and }. It helps you to expand or collapse some part(s) of your code to improve the visibility.
Unfolded if block Folded if block
When you write well-formed codes, a little - sign will be located every where that code folding option is available. It's just enough to click that - sign to fold and + sign to unfold a block of code.

CypressEditor.UI.Output Console

In addition to the classic DOS command prompt window, Cypress has an advanced internal output console. You can choose this behavior and switch between classic and internal console by using Options menu.
The Internal Console will close with pressing any key just like classic output window, but with some additional options:
  • Save output results as a text file.
  • Print output results to the printer or a file.
These simple options are available in context menu where you right-click on the console area.

puts "Hello word!"
