::b::Send % SubStr("a", 1)

Code: Select all

; #Requires AutoHotkey v2.0
::b::Send SubStr("a", 1)

Same for :X:b.

Thanks for this interim fix. I am also going to hope for an official revision!

Regex Error -8 usually indicates a catastrophic backtracking in my experience and I usually fix it by modifying the expression itself.

Commit 3c20468 fixes it. If you want to apply the fix prior to v2.0.12, it should be sufficient to update inc/identify_regex.ahk.
