Here is how to set Shift-Tab to zoom out:
In your Silent Hunter III/data/cfg folder is a file called commands_en.cfg. You can open it with a word processor (like WordPad or Notepad).
Inside it are all of the keyboard commands and they can be customized.
The only command associated with "Tab" seems to be [Cmd72], Cam_zoom_cycle. You can see that the command Cam_zoom_out [Cmd71] does not have a key assigned to it.
Code:
[Cmd71]
Name=Cam_zoom_out
Ctxt=1
[Cmd72]
Name=Cam_zoom_cycle
Ctxt=1
Key0=0x09,,"Tab"
After making a backup copy of commands_en.cfg for safety (name it "commands_en (old).cfg" or something similar), add the following line to the code for [Cmd71]:
The "s" between the commas means Shift in addition to Tab (you can also use a "c" instead of an "s" for Ctrl-Tab to be the zoom out).
The final code should look like:
Code:
[Cmd71]
Name=Cam_zoom_out
Ctxt=1
Key0=0x09,s,"Tab"
[Cmd72]
Name=Cam_zoom_cycle
Ctxt=1
Key0=0x09,,"Tab"
Save the file and the next time SHIII starts, Shift-Tab will zoom out on the F5 map screen (as well as on the F6 TDC screen).
