- Introduction
-
- Description
- Overview
- Highlights
- Requirements
- Contents of the Ctrl-Alt disk
-
-
- Description Ctrl-Alt frees up memory for large programs by
- swapping memory resident programs (TSRs) to your disk--giving you
- instant access to up to 24 popup programs such as SideKick, PC
- Tools, and Lotus Metro while using only 15K of memory.
-
- Overview When started, Ctrl-Alt individually loads each of your
- popup programs and writes a memory image of the popup to your
- disk. The memory used by the popup is then released back to the
- operating system. The Ctrl-Alt program itself remains resident
- and uses 15K of memory.
-
- Ctrl-Alt acts like any other popup program. When you press the
- Ctrl-Alt key combination, Ctrl-Alt displays a list of your popups
- and allows you to select one by moving the highlight bar and
- pressing Enter or by pressing a single key. A section of your
- memory is saved to disk, and the selected popup is loaded in its
- place. Pressing the popup's hotkey will activate the program as
- usual.
-
- When you exit the popup and Ctrl-Alt, the section of memory that
- was saved to your disk is restored, and you'll return to your
- original program.
-
- Highlights
-
- Ctrl-Alt can be popped up at any time, within any application,
- to load and run a TSR program.
-
- All of your TSRs are displayed in a menu and can be selected
- with a highlight bar or a single keystroke.
-
- Does not required setting aside memory for the largest TSR like
- similar programs.
-
- Compatible with all TSRs.
-
- Uses only 15K of memory. Frees all memory used by TSRs.
-
- Eliminates conflicts between TSRs and between applications and
- TSRs. Enables any TSR to pop up within a graphics program.

- Condensed Instructions
-
- The following instructions briefly describe the installation and
- use of Ctrl-Alt. If you are a knowledgeable computer user, you
- should be able to get Ctrl-Alt working by following these steps.
- More detailed information can be found in the sections,
- "Installation", "Using Ctrl-Alt", and "Command Reference".
-
- 1. Copy the file, ctrl-alt.exe, to the directory that has your
- utility programs.
-
- 2. Create a text file which lists your popup programs and the
- parameters needed to load them. Be sure to include a path
- for each TSR and its file name extension. For example, the
- following would load SideKick and PC Tools.
-
- \sk\sk.com
- \pctools\pcshell.exe /r
-
- 3. Run the Ctrl-Alt program and use the /f parameter to specify
- the text file which lists your TSRs. For example, if the
- file you created in step 2 is called ctrl-alt.txt, enter the
- command1
-
- ctrl-alt /fctrl-alt.txt
-
- 4. To use Ctrl-Alt, press the Ctrl and Alt keys simultaneously
- and follow the directions on the screen.

- Installation
-
- Copying Ctrl-Alt
- Configuring Ctrl-Alt
-
- Copying Ctrl-Alt The file, ctrl-alt.exe, should be copied to
- the directory on your hard disk you use for utility programs.
- You should have a command in your autoexec.bat file which
- includes this directory in your path so that your utility
- programs, including Ctrl-Alt, can be executed from any directory
- on your hard drive.2 The following installation procedure
- assumes you have a directory named \util in the root directory of
- drive C.
-
- 1. Insert the distribution disk in drive A.
-
- 2. Type [copy a:ctrl-alt.exe c:\util] (don't type the
- brackets).
-
- Configuring Ctrl-Alt Before running the Ctrl-Alt program, you
- must create a file which lists the popup programs you want Ctrl-
- Alt to load. The file should be a standard DOS text file and can
- be created using the DOS edlin program or any other editor or
- word processor. You can also create the file by copying from the
- console device as shown in the example below.
-
- Each line in the file should list the name of a TSR, including
- its path and file name extension, and the parameters, if any, you
- normally use to load the TSR. The following procedure will
- create a file, named ctrl-alt.txt, that will load Sidekick and PC
- Tools.3
-
- 1. Type [copy con \util\ctrl-alt.txt] and press Enter (don't
- type the brackets).
-
- 2. Type [\sk\sk.com] and press Enter.
-
- 3. Type [\pctools\pcshell.exe /r] and press Enter.
-
- 4. Press the F6 function key and Enter.
-
-
-
-
-
- ____________________
-
- 2Read about the path command in your DOS manual.
-
- 3This examples assumes ctr-alt.exe is in the directory
- \util, SideKick is in the directory \sk, and PC Tools is in the
- directory \pctools. If this is not the case on your system,
- substitute the correct directory names in this example.

-
- Using Ctrl-Alt
-
- The Ctrl-Alt command
- Popping up Ctrl-Alt
-
-
- The Ctrl-Alt command After you've created the file that lists
- your TSRs you can execute the Ctrl-Alt command. Use the /f
- parameter to specify the name of the file which lists your TSRs
- as shown in the example below.
-
- ctrl-alt /f\util\ctrl-alt.txt
-
- If, after executing this command, the message
-
- Bad command or file name
-
- is displayed, DOS was unable to find ctrl-alt.exe. The directory
- which contains ctrl-alt.exe must be in DOS PATH. If you received
- the message
-
- CTRL-ALT : error C0006: can't open program name list
-
- then Ctrl-Alt was unable to find the file you entered on the
- Ctrl-Alt command line. Be sure the file name you entered
- includes the correct file name extension and path. In other
- words, for the example above the file, ctrl-alt.txt, must be in
- the directory \util.
-
- Popping up Ctrl-Alt Press the Ctrl and Alt keys simultaneously
- to pop up Ctrl-Alt.4 Ctrl-Alt will display the names of your
- TSRs and allow you to select one by either moving a highlight bar
- and pressing Enter or pressing the letter next its name. After
- Ctrl-Alt loads the selected TSR into memory, it can be activated
- by pressing its hotkey, and will work just as if it had been
- resident in memory.
-
- When you exit the TSR, you can press Esc to return to the Ctrl-
- Alt menu, where you can select another TSR or press Esc to exit.
-
-
-
-
-
-

- 4Use the Ctrl key on the left if your keyboard has two Ctrl
- keys.

-
- Format
- Parameters
-
-
- Format The format of the Ctrl-Alt command is
-
- Ctrl-Alt [parameters]
-
- where
-
- [parameters]
- specifies the Ctrl-Alt parameters described in the following
- section.
-
- Parameters The following parameters can appear in the Ctrl-Alt
- command. The /f parameter, as described in the section "Using
- Ctrl-Alt", specifies the TSRs to be loaded and is required. The
- other parameters are provide to increase flexibility only and are
- not required. It is not necessary that you know how to use them.
-
- /?
- Display help.
-
- /dd:path
- Drive/path for paging file. This parameter specifies the
- location of the paging file, ctrl0000.dat, that Ctrl-Alt uses
- to store a memory image of your TSRs. If you omit this
- parameter, the paging file is placed in the root directory of
- the default drive. For example, this parameter places the
- paging file in the root directory of drive D, [/dd:]. If you
- need to put the file in a directory other than the root, you
- can specify a path also. For example, [/dd:\private\].
-
- /fname
- Program name list. This parameter specifies the name of the
- text file which lists the TSRs Ctrl-Alt should load. Each TSR
- should be listed on a seperate line. Include a path and a file
- name extension. Read the sections "Installation" and "Using
- Ctrl-Alt" for more information on the /f parameter.

-
- /hscancode
- Alternate hotkey. Use this parameter to change the hotkey that
- pops up Ctrl-Alt. scancode specifies the scan code of the key,
- in combination with the Alt key, that will pop up Ctrl-Alt.
- For example, the Alt-Left Shift hotkey would be specified by
- [/h42].
-
- Scan codes for the IBM PC keyboard can be obtained in any
- hardware reference manual; a few are listed below.
-
- Key Scan Code
-
- Left Shift 42
- Right Shift 54
- Space 57
- Esc 1
-
- /r
- Restore screen after loading TSR. After loading a TSR, instead
- of displaying the message "Program loaded", Ctrl-Alt will
- restore the screen as it appeared before Ctrl-Alt was popped
- up. This is useful when running a TSR, such as an envelope
- printing program, that reads characters from the screen.
- Remember to press the hotkey after loading the TSR and to press
- Esc after exiting the TSR to return to the Ctrl-Alt menu.
-
- /v
- Don't change video mode. This parameter causes Ctrl-Alt to
- never change the video mode of the display. Normally, when
- popping up in a graphics screen, Ctrl-Alt changes the display
- to text mode and then restores the original graphics mode when
- exiting. Although unlikely, if Ctrl-Alt is incompatible with a
- program that uses a graphics mode, you can avoid problems by
- using this parameter. Although the Ctrl-Alt menu or messages
- will not be displayed, Ctrl-Alt will work the same as usual--
- you just have to remember which letter loads a particular TSR
- and to press Esc twice after exiting the TSR.
