+## Modes
+1. Active Mode
+   - sends keystrokes to the active (the top window that you are focusing)
+   - the target window **MUST BE the TOP window**
+2. Inactive Mode
+   - sends keystrokes to any window you have chosen
+   - the target window **CAN be minimized**
+   - if the GTAV is the target widnow, this mode **WILL** shortly interrupt for your current task on the active window (losing focus, GTA pops up and     minimized repeatedly when keystrokes sent) 
+   - longer press interval recommended
+
 ## How To Use
 1. Run the executable / Download [AHK_v2](https://www.autohotkey.com/)
-2. Select the game that you want to AFK and place it as the top window
+2. Select the mode of the script and start AFK
 
 ## Remarks
 - The close button of the executable of this script *DOES NOT* kill the script but just close the GUI
 - Apart from the `Exit` button, you can use keyboard hotkey `Win+ESC` to kill the script
 - You can use hotkey `Win`+ `  to reopen the GUI
 - Key1 & Key2 cannot be set as special keys like `Ctrl`, `Shift` etc.
+- For GTAV, probably there is some mechanism has been deployed to avoid external automated keystrokes by scipt, the inactive mode is not using `ControlSend`      function, but using `Send` instead, which cause the forementioned interruption
