Add quotation marks around text blocks in editor fields: Select the lines you want to quote and press the toolbar button.
This WebExtension adds both a toolbar button and a keyboard shortcut ([Ctrl]+[Shift]+[E]) to add quotation marks around lines of text in a multiline text field (<textarea> ) of any web page. The typical usecases are text comments or bug reports which do not support html, markdown or other means of formatting text. If you want to visually separate your own comments from citations or code segments, you typically want to add a visual marker, like -------. This add on simplifies adding those markers. The type of markers is configurable.
