It's a script to toggle on/off a flying camera mode (from marvelous Flycam mod by Hermaen2000) with a press of an F8 button, instead of
opening developer console and writing/choosing right command every time. Of course for it to work poperly you have to install aforementioned mod first and have developer console enabled. Also your developer console opening button must be set to ` (grave) button - it is by default, AFAIK.

As I don't know if it's possible to bind a script to a button in DAO or the toolset, it is a standalone script created with AutoHotKey software.

Script was tested with GOG version of DAO Ultimate Edition, I can't say if Steam or Origin/EA App won't interfere with the script in some way, so if you'll find out, let me now in the comments. Of course any other script or software running in background, which uses F8 button, may conflict with this script.

.Exe file warning – READ IT
Optional file named "Flycam toggle script.exe" contain .exe file with compiled script. Some antivirus programs flag it as a trojan/malicious software (on Virustotal, 6/70 vendors flagged it as malicious). It is pretty common with AutoHotKey compiled scripts and it's 99% false-positive, for the uncompiled script is free of viruses. But I don't expect you to take my word for it, so if you don't won't to risk it (I don't blame you), download the main file.

What it does exactly?
It is a script running in the background, which works only if DAO window is the active one - it shouldn't interfere with any other program using F8 button. When F8 button is pressed in-game it does:
- "press" the grave button, opening developer console;
- "types" the right command to turn on or off the Flycam;
- "press" Enter button, running the command and closing developer console;
It all happens in less than a second, so you can say it's almost instant.

How to use .ahk file
Download "Flycam toggle script.ahk" or "Flycam toggle script.ahk Left-handed" file and extract it whenever you want. Now:
- If you're already using AutoHotKey then you know what to do – just run the script. Skip to "How to use in-game".
- If you're not using AutoHotKey, there are two ways:
1) download AutoHotKey (official site here) and install it. When it's done just run the script by double-clicking it. Skip to "How to use in-game".
2) download official AutoHotKey script compiler (official GitHub here), extract it and run the .exe file. Choose extracted FlyScript.ahk as a source file and choose the name for the compiled script. Next click "Convert" and close the AHK2EXE program. Now you can run created .exe file. Skip to "How to use in-game".

How to use .exe file
Download "Flycam toggle script.exe", extract it whenever you want and run it.

How to use in-game
When you'll run the script, you can finally use it. Fire up DAO, press F8 in-game and turn on Flycam mode. Press the button once more to turn Flycam off. Just remember to run the script file every time you want to play DAO, because the script will be ended with system shutdown.

If you have any problems with making it work, ask in the comments – I'll try to help, if my knowledge will let me.
