GNU Info (emacs)Tabs in PicturePicture Mode Tabs ================= Two kinds of tab-like action are provided in Picture mode. Use `M-<TAB>' (`picture-tab-search') for context-based tabbing. With no argument, it moves to a point underneath the next "interesting" character that follows whitespace in the previous nonblank line. "Next" here means "appearing at a horizontal position greater than the one point starts out at." With an argument, as in `C-u M-<TAB>', this command moves to the next such interesting character in the current line. `M-<TAB>' does not change the text; it only moves point. "Interesting" characters are defined by the variable `picture-tab-chars', which should define a set of characters. The syntax for this variable is like the syntax used inside of `[...]' in a regular expression--but without the `[' and the `]'. Its default value is `"!-~"'. <TAB> itself runs `picture-tab', which operates based on the current tab stop settings; it is the Picture mode equivalent of `tab-to-tab-stop'. Normally it just moves point, but with a numeric argument it clears the text that it moves over. The context-based and tab-stop-based forms of tabbing are brought together by the command `C-c <TAB>' (`picture-set-tab-stops'). This command sets the tab stops to the positions which `M-<TAB>' would consider significant in the current line. The use of this command, together with <TAB>, can get the effect of context-based tabbing. But `M-<TAB>' is more convenient in the cases where it is sufficient. It may be convenient to prevent use of actual tab characters in pictures. For example, this prevents `C-x <TAB>' from messing up the picture. You can do this by setting the variable `indent-tabs-mode' to `nil'. Note: Just Spaces. automatically generated by info2www version 1.2.2.9 |
