Simple command.cfg edit...

[SteamWake]

First of all thank you for your patience.

I am afraid to say I still cannot make it work.

Yes my Ctl key works I almost have worn out ctrl+pgup/down

I edited the header as advised.

I have no idea where the comments came from. Some mod I suppose.

[Contexts]
ContextsNb=13; max contexts nb is 16
Context0=None; default - should not be changed
Context1=Game
Context2=Pause
Context3=Spectator
Context4=Console
Context5=Museum
Context6=Effects
Context7=Final
Context8=Edit
Context9=Replay
Context10=ModalMsg
Context11=AdversarialMode
Context12=DeathEffect
[Commands]
CommandsNb=600
MaxKeyCommandsNb=190; Keys number shoud be smaller than this value (in order to accelerate the loading)
;Name = command name -> will be translated in command index
;Ctxt = command context(s) as indexes -> see [Contexts] section
;MnID = menu item id associated with this command
;Str = string id (from en_menu.txt) associated with this command
;KeyX = an entry containing <key_code>,<flags chars>,<help text id>; flags chars could be C=executed by the crew, R=repeat key, c=with control, s=with shift, m=only when mouse is captured (enabled), n=only when mouse is not captured (enabled)
;Page = <page_id>,<title_id>; associated page (only for user commands) and a title if is necessary

and the Cmnd's

I tried both of these

[Cmd192]
Name=Dive
Ctxt=1
Str=1030
Key1=0x44,c,"Ctl+D"
[Cmd193]
Name=Surface
Ctxt=1
Str=1031
Key1=0x53,c,"Ctl+S"

[Cmd192]
Name=Dive
Ctxt=1
Str=1030
Key1=0x44,cC,"Ctl+D"
[Cmd193]
Name=Surface
Ctxt=1
Str=1031
Key1=0x53,cC,"Ctl+S"

Maybe someone can put up a commands.cfg with Ctrl+S & Ctrl+D edited that works for them I can look at that.

Again thanks !
