If you have LibreOffice installed, you can preview LibreOffice documents in Windows Explorer. I wonder if it's possible to embed the document preview itself into the AutoIt window? Will the PDF preview work the same way out of the box? I know about: and: Before I focus on these threads, I'd first like to ask your opinion on whether this is possible? Or has anyone already tried it?

@jpm could you add this colors list to the HelpFile ?

As you run 32bit SciTE

I think You should move to WebDriver or WebView

@Jos in reference to https://www.autoitscript.com/trac/autoit/ticket/4087 I notice 2 issues, and maybe one of them is exact the same like in the ticket. Please focus on the comments in the following repro script #include <Array.au3> #AutoIt3Wrapper_UseX64=n Func _Test1() ; I assume _Test1() should always use highlighting style like localy defined function >> style.au3.17 ; ISSUE 1: but sometimes it switch to style.au3.0 ; just try to jump in Array.au3 UDF and jump back to this testing file / script EndFunc ;==>_Test1 Volatile Func _Test2() ; I assume _Test2() uses the highlighting style >> style.au3.0 ; ISSUE 2: IMHO it should be the same like for _Test1() I mean style.au3.17 instead style.au3.0 ; because the fact that it is still function names - defined in current filean thus should use >> style.au3.17 instead >> style.au3.0 EndFunc ;==>_Test2 Func __someinternal() EndFunc ;==>__someinternal _ArrayDisplay() What is your opinion?
