Dear Sysgate

Thank you for your response.

A very old linux book, linux in easy steps explains one of the modes very well:

"... the vi editor has one of the most bizarre and seemingly non-user-friendly interfaces ever invented... The first, and most important thing to learn about vi is that it has two modes. When you are in input mode, everything you type goes to the screen, and into the file you are editing. (the only exceptions to this are the curson-movement commands and the exit from input mode command) When you are in command mode, nothing you type goes into the file you are editing.; rather it will be interpreted as a command to the editor to do something. Understanding this is the key to understanding vi

An example

1. Start a new file called "testfile"

vi testfile

2. Press "i" to enter input mode. Type some text and press ESC

hello this is vi |

3. You are in command mode. Press O and the cursor will return to the beginning of the line. Press "x" 5 times and on each stroke on eletter of the Ist word will be deleted.

4. Now press ":" A colon prompt will appear on the bottom line. You are now in command of every mode. Type "q!" and press RETURN. This will quit vi without saving and return to you to the shell prompt (This has been one of the greatest mysteries. I used to get stuck in the vi prompt and it seemed impossible to get out of the vi prompt unlesss I shut down and restarted the computer !

The author goes on to present some useful commands and colon commands:

i Insert before the character the cursor is on etc

Cursor Movement

G Go to the last line of the file etc

Miscellaneous Commands

J join the current line to the next one etc.

Getting out of vi

:wq write file, then quit etc

Other colon commands:

:sh Run a temporary shell (CNTL-D to return)

Is there anything like this in the man pages or elsewhere that LISTS and explains various command modes?

Thank You.
Thanks.

LEARN ABOUT HPUX

xhpacknowledge

XHPAcknowledge(3X)														XHPAcknowledge(3X)

NAME

       XHPAcknowledge - Send an Acknowledge to an extended input device.

SYNOPSIS

       #include <X11/XHPlib.h>

       int XHPAcknowledge (display, deviceid, acknowledge)
	    Display	   *display;
	    XID       deviceid;
	    int       acknowledge;

ARGUMENTS

       display	   Specifies the connection to the X server.

       deviceid    Specifies the ID of the desired device.

       acknowledge Specifies the acknowledge to be sent.  Valid values are: GENERAL_ACKNOWLEDGE, ACKNOWLEDGE_1, ACKNOWLEDGE_2, ACKNOWLEDGE_3,
		   ACKNOWLEDGE_4, ACKNOWLEDGE_5, ACKNOWLEDGE_6, ACKNOWLEDGE_7.

DESCRIPTION

       This request is part of an HP-proprietary extension to X.  Its functionality has been superseded by the standard XChangeFeedbackControl
       request.  You should use XChangeFeedbackControl instead of XHPAcknowledge if possible.

       This request sends an acknowledge to an input device.  This allows a previously received prompt to be turned off.

       A prompt is an audio or visual indication that the program controlling the input device is ready for input.  The LED on an HP46086A
       buttonbox is an example of a prompt.  A program may indicate its status by turning on a prompt on the appropriate input device.

       Not all input devices support prompts and acknowledges.	Any device that does support a particular prompt will also support the
       corresponding acknowledge.

       To determine whether an input device supports a particular prompt and acknowledge, the io_byte field of the XHPDeviceList structure should
       be examined.  The format of this structure is described in the documentation for the XHPListInputDevices request.

RETURN VALUE

       none

DIAGNOSTICS

       BadDevice   An invalid device ID was specified.

       BadValue    An invalid acknowledge was specified.

FILES

       /usr/include/X11/XHPlib.h

ORIGIN

       Hewlett-Packard Company
