    In the previous issue was already
talking about the basic control keys
file shells IS-DOS. However, the system
control key IS-DOS, you may have guessed, this is not limited. 
The navigation system concept IS-DOS, and devoted the next part 
of our article.



      Control keys shell


    The system IS-DOS while working with the file wrapper to 
distinguish between two types control keys - keys that are 
reserved for the shell and the keys are user-defined. The first 
type are the keys: 

Q and CS +7 - move up

A and CS +6 - going down

O and CS +5 - switch to the left panel

P & CS +8 - move to the right pane

ENTER - the entrance to the subdirectory, run programs 
extent.txt 

Cs + ENTER - exit in the root directory of the current panel

CS + O - is the same for the left panel

CS + P - is the same for the right panel

CS + Q, SS + Q - move to the top of the directory

CS + A - go to the end directory

SS + CS - switching to an alternative to redundancy

CS +1 - the device on the left panel

CS +2 - select a device in the right panel

SPACE - mark file


    In addition, system-level utilities are reserved and the 
number keys from 0 to 9, but only three of them are not subject 
to redefinition, it is:


3 VIEW - Image files

7 crDIR - creating subdirectory

9 MENU - menu block device


    Keys 7 and 9 always rigidly adhered to the established in 
the resident program mkdir.res and gmen.res respectively, while 
the programs themselves can be modified, but their names must 
remain standard. Key 3 will always cause the viewer files 
according to the contents of a text file extview.txt. 
Appointment of the remaining numeric keys can be changed 
according to your wishes, but I recommend to stick arrangement 
adopted in the top row screen.



    Of the remaining keys are reserved
only key h. It is designed to
run the routine and acts like the key 3. The list of programs 
used to print files with different extensions contained in a 
file extprint.txt, which is placed in

directory SHELL. The principle of its construction
the same as that of the file extview.txt. The approximate 
contents of the file extprint.txt shown in Table. 4 

Table 4. Example file extprint.txt

Content
extprint.txt response to the key h

scr: Q: PRINT \ PL \ ps screen print file

as: Q: PRINT \ print Print Text

bat: Q: PRINT \ print Print Text

doc: Q: PRINT \ print Print Text

txt: Q: PRINT \ print Print Text

hlp: Q: PRINT \ print Print Text

wet: Q: PRINT \ print Print Text


    All keys except the above
can be programmed to call frequently
Use system utilities and application programs. Which of the 
program to assign to one or another key shell - you decide, but 
over the years of the IS-DOS has developed a kind of unofficial 
standard, formulated in 3.0. This standard is the most 
versatile and therefore I recommend stick it in their work to 
avoid ambiguity, and so forth inconvenience. 


    As you may have guessed, the appropriate keys and the 
called program is determined by the contents of a text file 
called extkey.txt. Availability This file is mandatory for

system, since without it will not work most of the keys of the 
shell. File extkey.txt is in the directory SHELL \ and

composed as follows. The first
character of each line - a symbol, obtained by pressing defined 
keys. When using the keys by which

Enter the symbol in the editor is difficult (some combination 
of SS), you can use the decimal key code, writing it after the 
symbol "'" (apostrophe). Decimal key code can be determined by

special utility ktest.com, you
can be found in the base package IS-DOS
3.0 and above in directory Q: RES \ KEY \.
