Next to the already known keys from the C64 - like Ctrl+Shift - some new (and I hope handy) keys are are introduced:
| Ctrl+Shift+m | switch Akku 8/16 Bit (M flag is not touched) |
| Ctrl+Shift+LeftArrow | Memory Mapping On/Off (aka Debug Mode. So hands off if you don't know what you are up to ;) |
| Ctrl+Shift+0 - 9 | Set $01 to #$3x (e.g.: Ctrl+Shift+5 is like lda #$35:sta 1) |
| Ctrl+Shift+x | switch X/Y 8/16 Bit (X flag is not touched) |
| Ctrl+Shift+f | follow Rep/Sep On/Off |
| Ctrl+Shift+h | 'verbose hunt/opcodehunt' Modus An/Aus, zeige ein paar mehr infos als nur die Adresse |
| Ctrl+Shift+v | switch VideoMode: (Vic, VDC 2531, VDC Super6 and ParDis (Experimental)) |
| Ctrl+Shift++ | more lines (only VDC2531 and Super6) |
| Ctrl+Shift+- | less lines (nur VDC2531 and Super6) |
| Ctrl+Shift+Cursors | Move cursor to the screen borders (Ctrl+Shift+Down = move to last line) |
| Ctrl+Shift+p | set mapping mode to 'program bank' |
| Ctrl+Shift+d | set mapping mode to 'data bank and zeropage' |
| Ctrl+Shift+n | set mapping mode to 'none' |
Ctrl+Shift+m and x only change internal flags for akku and register sizes. The M and X flag of the processor status is not altered.
The videomode 'VDC2531' uses the 80 colums screen of a C128. Change the number of lines from 25 up to 31 with Ctrl+Shift++ and Ctrl+Shift+-.
The 'super6' mode is similar to 'VDC2531' but uses another charset which is just 6 pixels high. This way more lines fit onto the screen. The total amount depends on your (hardware-) monitor. The number of lines is changes the same way as in the 'VDC2531' mode.
As both modes use the VDC chip they are only available on a C128.
