Understanding the various editors and the application designer
As you create different artifacts in web or mobile applications, you will see different options and editors that will help you to view and modify the artifacts and pages. So, it is really important to understand each and every option and the editors that VB provides.
The designer is used to design the application flows, pages, variables, types, Action Chains, JavaScript, and so on. For each and every artifact, you will deal with different editors and options. For example, in order to create a new variable, you have to switch to the variable editor and have to deal with different options. You have access to the source code of artifacts in order to modify them using the code editor.
You can simply switch between different editors by clicking on the different available tabs.
