Horizontal scrolling is now available in CCA EMACS. The command C-X < (^R Scroll Left) will shift the text in the current window to the left, while C-X > (^R Scroll Right) will shift the text in the current window to the right. Numeric arguments can be used with both commands to specify the number of columns to be shifted; the default number is one. When text in a window has been shifted to the left, exclamation points will appear in column zero of each line to indicate that further text exists to the left. When point is located in this unseen text, the cursor will be positioned at the exclamation point. Wrapped lines are automatically truncated at the right margin whenever text in a window is shifted left, regardless of the setting of Truncate Wrapped Lines. However, if Truncate Wrapped Lines is zero, the long lines will once again wrap when the text is shifted back to its original position. When text is shifted left, the command C-X = (What Cursor Position) will display an additional field at the end which specifies the first column of text which is shown on the screen.
