Optionals

Another way to create and select optional placeholders is command choose-optional (mouse button: MENU), which lists all optional syntactic categories at the mouse position in a popup menu. (MENU is typically the right mouse button.) Selection of a menu item inserts and selects that optional placeholder.

Aim the mouse pointer just to the right of one of the semicolons separating the statements and press MENU. Move the mouse pointer down the menu to the statement_list item and release it. Repeat the process at various locations.

Optional items are also listed in the Transforms menu.

X Windows Optional items at the insertion cursor are shown in the context pane as buttons, but with a different style from transform buttons. Selection of these buttons causes the corresponding optional placeholders to be inserted. Move the insertion cursor to the right of the is keyword in the procedure declaration. Click the declaration_list button in the context pane to insert a declaration placeholder.

NT There is a shortcut to the mouse menu for the transforms, key: Shift+Mouse-Btn3. Move the insertion cursor to the right of the is keyword in the procedure declaration. Choose the declaration_list transform from the transforms menu to insert a declaration placeholder.
