See the sections on this page for the Textual Editor features that can ease your workflow. See also Command Palette and Find dialog pages.

Autocompletion

The Textual Editor provides an autocompletion function.

• Invoke the autocompletion dialog by pressing Ctrl+Space shortcut keys. Use the up and down keyboard buttons to navigate the suggestions and click the selection. 

Use the Preferred Element Name for Autocompletion environment option to specify which element name should be suggested in context-sensitive autocompletion.

Two types of autocompletion may be suggested in the autocompletion dialog:

• Snippets
  • Suggests keywords. Selecting the keyword creates the keyword with its notational structure.
  • Snippets are indicated with the square symbol.
    
• Context-sensitive autocompletion
  • Suggests already-created elements' names and library packages.
  • Context-sensitive autocompletion is indicated with a box symbol.
    

Folding the textual notation

Folding the element's body allows you to easily hide it in the textual notation if its visibility is not needed. It can be useful when the textual notation is extensive. The folding is only persistent while the Textual Editor is open; the element is unfolded upon the reopening of the Textual Editor. 

To fold/unfold the textual notation

1. Locate the element whose body you want to fold.
2. Move the cursor to the left margin of the element keyword, next to the line number.
3. Do one of the following:

   1. Folding.

      1. Click the down-facing arrow to fold the body of an element.

         

   2. Unfolding.

      1. Click the right-facing arrow to unfold it.
         

      2. Click the three dots next to the opening braces of the folded body.
         

You can also hold Shift and click the arrow. If the selected element contains elements with bodies, the latter are folded upon the first click of the arrow (this applies only to the first level of elements with bodies). The second click folds the entire body of the selected element. Unfolding works the same way: the first click unfolds the selected element, and the second unfolds the contained elements with folded bodies.
