Scheme

• Execute will execute the definitions window.
• Break will break the current evaluation.
• Indent will correctly indent the selected text. (This can also be done just by pressing the Tab key on your keyboard.)
• Indent All will correctly indent all of the text in the ``active buffer'' (the buffer where the cursor currently is).
• Comment Out will put ``;'' characters at the beginning of each line of the selected text except for lines that already have a ``;'' at the very left-most position.
• Uncomment will remove all of the ``;'' characters at the left of the lines in the selected text. It will remove ``;'' which come after spaces but before other text. If multiple blocks of ``;'' exist (eg. ``;; ;'') it will only delete the left-most block.
