Just an idea I got while experiencing the "stuck" TDC screen:
it should be possible to change that with a key... and I found the command #131 active/deactive autoupdate of TDC.
I set the "t"-key to use it with that to set autoupdate on/off at once while having the TDC screen opened/closed... whatever etc.
here's the change I made:
[Cmd131]
Name=Toggle_TDC_autoupdate
Ctxt=1
Key0=0x54,,"T"
MnID=0x3F010017
of course I deactivated the key in the flak command:
[Cmd21]
Name=A01gun_camera
Ctxt=1
;Key0=0x54,,"T"
Page=0x3A000000,3710
GoBack=Conning_deck_camera
as I toggle through the flak with F11
Is this an idea? or what

- is the ideal solution for that problem imho but the drawback is you have te keep in mind to active again if you want to make changes... the advantage is you can set the TDC to autoupdatewithout moving the mouse by just hitting "T"
I would also like to open and close the TDC with the G-key but cannot find the appropriate command in the cfg....

- am I blind or what
... and yeah... I am a big fan of keyboard-shortcuts

(I also changed the "ENTER" back to fire the Torpedo)
