CONTROL
This key is similar to 'shift' in that it generates a new set of
ASCII codes.
By holding down 'CTL' and pressing an alphabetic key, a control
code is generated e.g.
1
CTL A' clears the screen and 'CTL G'
sounds the bleeper. (Note: this function is inhibited in the
file manager).
Another use of control is for adjustment of the LCD display
viewing angle. By pressing 'CTL' and either up or down arrow
the viewing angle may be changed to suit the user. This function
is always active.
FUNCTION KEYS
The CTL/FN key may also be used to generate key sequences known
as function keys. These strings may be used for frequently used
commands and are present within system programs (DEMOS, Basic,
etc.) They are operated in a .similar fashion to control, but
pressing a numeric key 1-8, giving the eight function keys.
The commands implemented are displayed on the bottom line of
display (this may be turned off, see the LBL key).
Within Basic programs the key may be initialised to new
functions, see section 4.5.4 FUNCTION KEYS.
ESCAPE AND BREAK
'ESC' is an upper-shifted key used to break into and terminate
execution of HUNTER Basic.
'BREAK' (BRK) is used to interrupt a Basic program. See 'ON
BREAK' in Part 5, BASIC FUNCTIONS. Break is also available for
CP/M programs and in terminal mode.
INS AND LBL
'INS' will return the virtual screen window to its original
position.
'control INS' will reverse the operation of the 'SHIFT' key on
the characters
A - Z, providing a 'CAPS' function.
'LBL' switches the function line display on and off. LBL is an
upper shifted key.
