What is the best autoclicker/ which do you use?
		
		
	 
I've been using AutoHotkey, but it's Windows only. You can download it in here:

With AutoHotkey you can use this script to make an "autoclicker", something that presses a key repeatedly to skip lots of dialogue in a game:
	
	
	
		Code:
	
	
			Ins::
While Getkeystate("Ins", "P")
{
    Send, {Enter down}
    sleep, 75
    Send, {Enter up}
    sleep, 75
}
Return
	 
 When using this, holding the Insert key will cause repeated Enter key presses. You can also tap Insert once if you just want a single press. 
I chose Insert because it's a key I never use, but you can find other key names in this page:

Alternatively, if the game only uses 
mouse clicks, you can use this variation:
	
	
	
		Code:
	
	
			Ins::
While Getkeystate("Ins", "P")
{
    Click, Left
    sleep, 150
}
Return
	 
 Holding Insert key will cause repeated mouse clicks. You can also tap Insert for a single mouse click.
To actually use these scripts, you copy-paste each code to a blank Notepad document and save the first as "insert_to_enter_repeat.ahk", and save the second as "insert_to_mouseclick_repeat.ahk". Save these files in the 
same folder as the Autohotkey executable (AutoHotkeyA32.exe).
You can then right-click AutoHotkeyA32.exe, choose Send To -> Desktop (Create Shortcut), then right click the new shortcut on your desktop, choose Properties and then in the command line add a space and the name insert_to_enter_repeat.ahk at the end, so that the shortcut will autorun the script. To clarify, the command line will look something like this, without the quotes: "[path_to_autohotkey]\AutoHotkeyA32.exe insert_to_enter_repeat.ahk".
You can repeat this to create as many shortcuts as you want to as many different scripts.
I use this for many games, even non-Renpy ones.
