| package Sample.Function_Key_Setting is |

| procedure Push_Environment (Key : in String; |
| Reset : in Boolean := True); |
| -- Push the definition of the current function keys on an internal |
| -- stack. If the reset flag is true, all labels are reset while |
| -- pushed, so the new environment can assume a tabula rasa. |
| -- The Key defines the new Help Context associated with the new |
| -- Environment. This saves also the currently active Notepad. |
| |
| procedure Pop_Environment; |
| -- Pop the Definitions from the stack and make them the current ones. |
| -- This also restores the Help context and the previous Notepad. |

| -- false otherwise. |
