Document+Edit → Toggle Line Wrap (Ctrl + Shift + Y): Turns on line wrapping in the editor panel if it was off and vice versa. It has the same effect as the Line wrap preference.

Document+Edit → Toggle comment (Ctrl + Shift + ,): Comment the current selection of the current editor. If the selection already contains a comment the action removes the comment from around the selection. If there is no selection in the current editor and the cursor is not positioned inside a comment the current line is commented. If the cursor is positioned inside a comment then the commented text is uncommented. The action is also available on the popup menu of the editor panel.
