Editing Outlines
Text editing within the Koutliner works just as it does for other buffers, except when you need to deal with the structural components of an outline. Within the contents of a cell, all of your standard editing keys should work properly. You can just type in text and the left and right margins of the lines will be maintained for you. See Filling, for the times when you need to refill a paragraph or to control when filling occurs.
Don’t invoke editing commands with {M-x command-name RET} since the Koutliner uses differently named commands made to act like the regular editing commands. Koutliner commands, however, account for the structure and indentation in koutlines.
You may use the mouse to select parts of the contents of a single cell for editing. But don’t drag across cell boundaries and then edit the selected region, since that will destroy the outline structure.
