I am normally using COMAL-80 Version 2.02, which is Commodore C128 
compatible! Being used to some luxury functions like clearing the editor
screen etc., with a KEY-combinations, i was wondering if Amiga also is 
offering the same and, indeed, it does. That's actually quite handy
and very useful!


FIND THEM ALL HERE BELOW:
{I mostly used CTRL + L to CLEAR the Screen because Editor Screen got messy
{very quickly after trying many things out} 


CONTROL KEYS {AmigaCOMAL v2.03}
{NOTE: Taken from the COMAL 2.0 Demo Disk and made it better readable}
{But there is also a version in Comal Today magazine}

SPECIAL KEYS
----------------------------------------------------------------------------
Some of the keys have special functions as described below.


<ESC>
In command mode this key works like <AMIGA>+<S>.
For example, press <ESC> during the execution of a LIST or DIR command to 
stop the command.


<F?> 
The function keys have numbers from 1 to 10 (i.e, <F1>, <F2>, <F3>...). 
Each key has a predefined text attached. Press the key and this text will 
be output on the screen just as if you had typed each character of the text,
one by one.


<DEL>
Deletes the character at the cursors position and the rest of the line is 
moved one character to the left.


<-    
The back space key works like the <DEL> but instead of deleting the 
character at the cursor position, the character immediately to the left
is deleted. Consequently the key has the same effect as <LEFT> 
followed by <DEL>.


<INS> 
Toggles the insert flag. You will move from insert mode to overwrite mode
or back again. This key is on the numeric keypad. Use <Shift>+<0> 
(shifted zero on the keypad).


<ALT>+<DEL>
Deletes the cursor line and scrolls the remaining lines up.


<ALT>+<INS> 
Inserts an empty line at the cursor position and scrolls the remaining 
lines down.


<ENTER>
The Enter keys are very important in AmigaCOMAL. Depending upon your 
computer model, the word ENTER or RETURN or just a broken arrow symbol
will be on the keytop. There may be two of the keys on the keyboard, 
each identical in function. Press one of these keys and AmigaCOMAL reads
the contents of the line containing the cursor. In direct mode, 
if the line contains a command, the command will be executed. If it 
contains a program line, the line will be checked for correct syntax and 
then stored. During program execution, pressing this key signifies the
end of your INPUT.


<CURSOR KEYS>
Used to move the cursor. If one of these keys are pressed (UNSHIFTED) the
cursor moves in the corresponding direction. If the cursor hits the bottom
of the window and the bottom line (or previous line) contains a program
line, the program will be scrolled down. Likewise moving up past the top.


<SHIFT>+<CURSOR KEYS>
Moves cursor to the indicated edge of the window. <SHIFT>+<RIGHT> goes to 
the end of the line. If you are already at the top of the screen, 
<SHIFT>+<UP> will page the program listing up
(if the top line listed is a program line). 
Likewise with <SHIFT>+<DOWN> at the bottom of the window. 
<PAGEUP> and <PAGEDOWN> on the numeric keypad
(used with <SHIFT>) work just like <SHIFT>+<UP> and <SHIFT>+<DOWN>.


<CTRL> + <C> 
Repeats a FIND or CHANGE command. See description of FIND and CHANGE in
Chapter 2.


<AMIGA> + <S> 
This key combination works much like <ESC>. In command mode the effect is 
exactly the same: to stop the execution of a command. But in addition, 
this key combination also stops the execution of a program.


<AMIGA>+<S> 
is a short cut for the STOP menu.


<AMIGA> + <N>
A short cut for the NEW menu. The effect is the same as typing the 
NEW command.


<AMIGA> + <R>
A short cut for the RUN menu. The effect is the same as typing the 
RUN command.


<AMIGA> + <Q>
A short cut for the QUIT menu. The effect is the same as typing the 
BYE command.


<AMIGA> + <P>
A short cut for the PAUSE menu. By pressing this key combination 
(or by selecting the PAUSE menu) a running program will be put into the
waiting state until <AMIGA>+<C> is pressed 
(or the Continue menu is selected).


<Amiga> + <C>
A short cut for the Continue menu. Being in command mode the effect is 
the same as typing the CON command. If you are in the Pause state the 
program execution will be resumed.


PEN COLOR
Choose one of 32 colors by printing a CHR$(X)
where X is a value between 128-159 (hex $80-$9f).

	Example:
	PRINT chr$($80+3)  // sets color to 3

Print a CHR$(17) before and after the color code
to shift to the next 32 colors in Extra Half
Bright mode (some early Amiga models may not have
this mode).

	Example:
  	PRINT chr$(17),chr$(130),chr$(17) //color to 35


BACKGROUND COLOR
Print a CHR$(16) before and after the color code
to set the background to the specified color.

	Example:
	PRINT chr$(16),chr$(130),chr$(16)//background 3


BIT PLANES
You must have installed AmigaCOMAL with enough bit planes for the screen
to see all the colors.It takes 6 bit planes to display all 64 colors in 
Extra Half Bright mode.
