Special Keys used to change the Runtime Functionality of a Page +======================================================================= + + when in mixed HP/VT mode, one has two types of function key labels + on screen, user function keys and system function keys. they are + accessed by using the CTRL key while pressing a function key. + + the function key labels are NOT available in pure VT220 mode--although + the function keys are still active + + the user function keys and their labels can be reprogrammed by use of + escape sequences. + + in system function key mode, several pre-programmed functions inside + the emulator can be toggled, currently implemented are: + + - CTRL-F1, toggle 80/132 columns + - CTRL-F2, soft reset emulator + - CTRL-F3, toggle force 24 lines mode + - CTRL-F4, toggle keyboard debugging (if compiled in) + - CTRL-F5, toggle the audible beep generation + - CTRL-F6, toggle 7/8 bit char width + - CTRL-F7, toggle display functions. this means that control codes + in the range 0x00 to 0x1f are not EXECUTED by the emulator + any longer, but displayed on the screen + - CTRL-F8, toggle automatic cursor wraparound at end of line + + these functions operate just for the selected page + + +III.
