Anyway ... aren't these key replacement "shortcuts" configurable ?

Both SPACE and ENTER not used for any plus function with ALT in normal Enterprise mode.

But maybe SymbOS uses alt+enter for something ... in this case Prodatron is looking for empty combinations for SymbOS not for EXOS editors ... isn't he ?

Now I saw to CPC's keyboard ...

How I see CPC has no ALT at all ... so with ALT you can double the EP keys, cannot you ?

In this case alt+enter can be the little enter of CPC, if SymbOS uses that key frequently ...

And alt+space and alt+right shift can be mouse buttons ...

And alt+f7,f8 can be f9,f10 ...

And such ... but everybody will be able to decide the good combinations only in practice ...

Things can be difficult in the real world ...

I wonder if it would be possible to fake an EXOS environment (RST, replacement memory allocation and video and editor device etc) in the SymbOS app's memory space, and then run IS-BASIC in a SymbOS window!

Interesting idea!

Would it be an IS-BASIC related thing, or are we talking about every EXOS based software using the standard EDITOR device or such ?

The ultimate aim would be to provide a full EXOS-compatible environment so you can run any standard EXOS program. But just IS-BASIC would be a very cool start! Of course anything that fiddles with the LPT isn't going to work, so that rules out a lot of games I guess.

As far as I can tell it's not so easy, at least the memory paging should be modified to use them via SymbOS functions, etc. Same for IS-BASIC. Maybe it's not impossible But really at least direct hw I/O must be somehow avoided especially the direct modification of 0xB0-0xB3 ports. Also some new EXDOS (fish?) should be written to use things via SymbOS and not direct I/O. And yes, directly setting LPT etc wouldn't be too good either However what I think for a more simple start: the possibility to run CP/M applications on the top of SymbOS somehow. In theory some "interface" CP/'M CBIOS and BDOS should be written with the only purpose is to "transfer" calls for their SymbOS equivalents. And at least you can run multiple CP/M programs in parallel. There are some useful CP/M programs like even compilers which would used then with SymbOS too. And CP/M is simple enough (at least more simple than the EXOS/EXDOS realm) to do. In my opinion at least!

Well, it's funny but I never thought about having a real INS key in SymbOS, that's probably because of my CPC origin...
Ok, I will first use the INS key. Problem with Alt+Return (Alt+Enter on the EP) is, that this key-combination is already used for switching between fullscreen- and window-mode for the SymShell how it was in Windows.

Most keys are configurable...

but some for special functions are hardcoded.
F9/F10 can be emulated with ALT+F7/F8, but then you loose the possibility to have ALT+F9/F10, too. In this case it's really up to the user to do the configuration he likes.
Yes, ALT on CPC is "Copy", on MSX it's "Graph" and on PCW it's "Extra", the Enterprise is the only one, which has a real Alt-Key!
