GNU Info (info-stnd.info)Miscellaneous CommandsMiscellaneous Commands ********************** GNU Info contains several commands which self-document GNU Info: `M-x describe-command' Read the name of an Info command in the echo area and then display a brief description of what that command does. `M-x describe-key' Read a key sequence in the echo area, and then display the name and documentation of the Info command that the key sequence invokes. `M-x describe-variable' Read the name of a variable in the echo area and then display a brief description of what the variable affects. `M-x where-is' Read the name of an Info command in the echo area, and then display a key sequence which can be typed in order to invoke that command. <C-h> (`get-help-window') <?> <F1> (on DOS/Windows only) h, vi-like operation Create (or Move into) the window displaying `*Help*', and place a node containing a quick reference card into it. This window displays the most concise information about GNU Info available. <h> (`get-info-help-node') <M-h>, vi-like operation Try hard to visit the node `(info)Help'. The Info file `info.texi' distributed with GNU Info contains this node. Of course, the file must first be processed with `makeinfo', and then placed into the location of your Info directory. Here are the commands for creating a numeric argument: <C-u> (`universal-argument') Start (or multiply by 4) the current numeric argument. `C-u' is a good way to give a small numeric argument to cursor movement or scrolling commands; `C-u C-v' scrolls the screen 4 lines, while `C-u C-u C-n' moves the cursor down 16 lines. `C-u' followed by digit keys sets the numeric argument to the number thus typed: `C-u 1 2 0' sets the argument to 120. <M-1> (`add-digit-to-numeric-arg') <1>, vi-like operation <M-2> ... <M-9> <2> ... <9>, vi-like operation <M-0> <0>, vi-like operation Add the digit value of the invoking key to the current numeric argument. Once Info is reading a numeric argument, you may just type the digits of the argument, without the Meta prefix. For example, you might give `C-l' a numeric argument of 32 by typing: C-u 3 2 C-l or M-3 2 C-l <M-> (`add-digit-to-numeric-arg' <-> To make a negative argument, type `-'. Typing `-' alone makes a negative argument with a value of -1. If you continue to type digit or Meta-digit keys after `-', the result is a negative number produced by those digits. `-' doesn't work when you type in the echo area, because you need to be able to insert the `-' character itself; use `M--' instead, if you need to specify negative arguments in the echo area. `C-g' is used to abort the reading of a multi-character key sequence, to cancel lengthy operations (such as multi-file searches) and to cancel reading input in the echo area. <C-g> (`abort-key') <C-u>, vi-like operation Cancel current operation. The `q' command of Info simply quits running Info. Under `--vi-keys' (Note: --vi-keys), you can also exit with `:q' or `ZZ'. <q> (`quit') `C-x C-c' `:q', vi-like operation `ZZ', vi-like operation Exit GNU Info. If the operating system tells GNU Info that the screen is 60 lines tall, and it is actually only 40 lines tall, here is a way to tell Info that the operating system is correct. `M-x set-screen-height' Read a height value in the echo area and set the height of the displayed screen to that value. On MS-DOS/MS-Windows, this command actually tries to change the dimensions of the visible screen to the value you type in the echo area. Finally, Info provides a convenient way to display footnotes which might be associated with the current node that you are viewing: <ESC C-f> (`show-footnotes') Show the footnotes (if any) associated with the current node in another window. You can have Info automatically display the footnotes associated with a node when the node is selected by setting the variable `automatic-footnotes'. Note: `automatic-footnotes'. automatically generated by info2www version 1.2.2.9 |
