If the IDE is configured, it can be used directly without any configuration modification.

Not that I know of.

But you can
- get the portable version (zip) at https://www.autohotkey.com/scite4ahk/
- copy a portable v2 AutoHotkey64.exe to the correct relative folder path
- quickly apply the settings from this link once and set the S4A toolbar HH icon menu to v2 mode

Good enough?

I downloaded two files at https://www.autohotkey.com/scite4ahk/:
Step 1 Installation: AutoHotkey_2.0-rc.1_setup.exe
Step 2 Installation: SciTE4AHK_v3.1.0_Install.exe
Then ahkV2 worked。Thanks a lot. I need ahkV2 very much.
