Number	Description
1	The Script Editor controls, containing the following buttons: : Validates the current script. If no syntax errors are detected, the status bar (2) and the validation indicator (3) turns green. In case of errors, they turn red. Hotkey: F6. : Deletes the entire script after confirmation. : Comments out the active line (that is, where the prompt is located), or the selected line(s). Clicking the button multiple times when the same line(s) are selected adds multiple comment tags to the selected line(s). : Uncomments the selected comment line(s).
