GNU Info (emacs)Basic PictureBasic Editing in Picture Mode ============================= Most keys do the same thing in Picture mode that they usually do, but do it in a quarter-plane style. For example, `C-f' is rebound to run `picture-forward-column', a command which moves point one column to the right, inserting a space if necessary so that the actual end of the line makes no difference. `C-b' is rebound to run `picture-backward-column', which always moves point left one column, converting a tab to multiple spaces if necessary. `C-n' and `C-p' are rebound to run `picture-move-down' and `picture-move-up', which can either insert spaces or convert tabs as necessary to make sure that point stays in exactly the same column. `C-e' runs `picture-end-of-line', which moves to after the last nonblank character on the line. There is no need to change `C-a', as the choice of screen model does not affect beginnings of lines. Insertion of text is adapted to the quarter-plane screen model through the use of Overwrite mode (Note: Minor Modes). Self-inserting characters replace existing text, column by column, rather than pushing existing text to the right. <RET> runs `picture-newline', which just moves to the beginning of the following line so that new text will replace that line. Picture mode provides erasure instead of deletion and killing of text. <DEL> (`picture-backward-clear-column') replaces the preceding character with a space rather than removing it; this moves point backwards. `C-d' (`picture-clear-column') replaces the next character or characters with spaces, but does not move point. (If you want to clear characters to spaces and move forward over them, use <SPC>.) `C-k' (`picture-clear-line') really kills the contents of lines, but does not delete the newlines from the buffer. To do actual insertion, you must use special commands. `C-o' (`picture-open-line') creates a blank line after the current line; it never splits a line. `C-M-o' (`split-line') makes sense in Picture mode, so it is not changed. `C-j' (`picture-duplicate-line') inserts below the current line another line with the same contents. To do actual deletion in Picture mode, use `C-w', `C-c C-d' (which is defined as `delete-char', as `C-d' is in other modes), or one of the picture rectangle commands (Note: Rectangles in Picture). automatically generated by info2www version 1.2.2.9 |
