Mode of Operation
The Screen Editor has two modes of operation: Edit Mode and Input Mode. You can identify the current mode by looking at the Status/Command Line at the bottom of the screen. It shows the current mode and the item-id of the item being edited.
Edit Mode
Edit Mode allows you to modify items that already have some characters in them. You automatically enter Edit Mode when you begin to edit an item that already exists.
Press I in Edit Mode to change operation to Input Mode.
All of the Screen Editor commands described in Screen Editor Commands are used in Edit Mode.
Input Mode
Input Mode allows for input of new characters. You cannot use Screen Editor commands in Input Mode because they are interpreted literally as characters, not as commands.
You automatically enter Input Mode when you begin to edit a new item.
You can type any number of characters per line with characters automatically wrapped to the next row when the current row is full. Each time you press RETURN, a new line is started. If there are no characters on a line, a null line is created.
Press ESC to return operation to Edit Mode.
