Novice tweaker needing assistance

[Bosje]

ok here goes nothing

my current setup is: 1.5, PE3.3, RFB1.5, RSRDC1.4 with patches

it introduces several minor issues, some of which I managed to solve all by my lonesome.

the Home and End keys for strafing up/down on the cameras got somehow disabled. I removed the ";" in front of the setkey lines in commands.cfg and that fixed it. no ill side-effects observed so far

The B key for toggle general quarters is removed by 1.5, I put some ";" in front of all B setkey lines I could find and copy pasted the line for 'toggle binoculars' over to the already present but keyless 'toggle general quarters' command. that now looks like this:

[Cmd436]
Name=Toggle_battle_stations
Ctxt=1
Key0=0x42,,"B"

and it seems to work fine at first glance.

the trouble is, I don't know exactly what I'm doing: what does that ctxt=1 and 0x42 mean exactly and what am I screwing up by tweaking my game like this?

the next step is a more complicated one
My camera is somehow corrupted, I can not click the sonar and radar consoles with the mouse from the conning tower without screwing up something somewhere. I have no clue where the fault lies, I didn't do any tweaking to any relevant commands afaik. all i know is this: when the game setup has a conning camera fixed in one place, the error does NOT occur. that's to say 1.5 without mods works fine, and the ROW camera mod 2b also removes the error.

here is what happens exactly: I click the sonar console and I am put in front of the sonar. i can work the sonar and I can hit the right mouse button. that right mouse button (previous camera afaik) puts me back in the control room (whereas the previous camera actually was the conning tower from where I clicked the sonar console)
so far so good, but when i turn around inside the control room, look up to the hatch and click the highlighted 'conning tower' to climb up there, I get moved into a big black wormhole with 'camera out of sectors'. moving around for a bit to try to back to known territory doesn't get me anywhere, I have no idea where the camera is at.

but
common sense tells me that this is due to the way the game tries to handle both US fleet boats and Uboots.

[Cmd11]
Name=Interior_aft_camera
Ctxt=1
Page=0x33000000,3704
GoBack=Interior_fore_camera

[Cmd12]
Name=Interior_radio_camera
Ctxt=1
;Key0=0x78,,"F9"
MnID=0x3F020007
Page=0x33000000,3708
GoBack=Interior_fore_camera

[Cmd13]
Name=Conning_tower_camera
Ctxt=1
Page=0x33000000,3715
GoBack=Interior_fore_camera

there, you see. that one has F9 not functional. instead, the functional F9 can be found here, which is exactly where it puts me in the game: the radar console

[Cmd530]
Name=Radar_view_ascope
Ctxt=1
Key0=0x78,,"F9"
Page=0x33000000,3725
GoBack=Interior_fore_camera

There are several other F9 commands in the commands.cfg. all of em with ";" in front of them. so that makes sense. Name=Interior_radio_camera (above) is one of them, which I assume is the fixed-in-place-conning tower camera from stock, a remnant of the original clean 1.0 installation before patching. Is that assumption correct?

My limited brain tells me that it might be possible solution to change the "GoBack=Interior_fore_camera" into "GoBack=Interior_radio_camera" and launching the game again to see what that does.

Am I doing things even remotely right? Or am I making a complete mess of weird and wonderful files hidden deeply inside my games folder which will completely wreck the whole setup?

any feedback would be much appreciated.

Edit: i can't reproduce the bug in the IXD2 as the sonar and radar consoles can not be activated through the mouse from the radio room. the guys just turn towards me as they did in good old SH3

Edit: what is the proper wording to assign the numpad enter key to the "time compressin 1x" command?

[Cmd6]
Name=Time_compr_normal
Ctxt=1,2,6,9
Key0=0x6D,s,"Shift+Npad -"
Key1=0x6D,s,"Numpad Enter"

ah, edit the edit: got that sorted by copy pasting the line from my SH3 folder
key1=0x0D,, "enter" sorts it out, i assume this is something to do with the way the game recognises my keyboard or something
