Squad ALPHA

For my installation, the following steps correctly bound the Left Ctrl key to the 'Adjust' control:

1.-Exit Arma 3.
2.- Open in Notepad or another text editor the text file "{yourProfileName}.Arma3Profile". This text file is located either in "c:\Users\{yourUserName}\Documents\Arma 3" or "c:\Users\{yourUserName}\Documents\Arma 3 - Other Profiles".
3.- Insert '29' into 'keyAdjust[]={};', as per Das Attorney's post:

keyAdjust[]={29};

In my {userName}.Arma3Profile text file, 'keyAdjust[]' is assigned its value on line number 15.
4.- Restart Arma 3.
