Text Editor Buttons

This button...	Does this...
`Cancel`	Closes the editor without making any changes to the text. If you have made changes to the text, G2 displays a confirmation message. `Cancel` is always visible.
`End`	Accepts the text and closes the editor. `End` is only visible when the current text is a valid, complete statement. The `End` button does not appear when you enter a value into a simple attribute, or when the statement is not valid or complete.
`Paste`	Inserts the top-most piece of text from the scrapbook at the current cursor location. `Paste` is only visible when text is in the scrapbook.
`Redo`	Redoes the last edit you undid using `Undo`. (You can also use the keystroke command Alt + r.) `Redo` is only visible when you have undone one or more edits by using `Undo`.
`Undo`	Undoes the last edit you made in the editor. (You can also use the keystroke command Alt + u.) `Undo` is only visible when you have made text edits.
`Update`	Accepts the current text in the editor without closing the editor. `Update` is particularly useful for editing procedures. `Update` is not available when creating new statements or rules, when saving and loading KBs, or when using the Inspect facility.
