P: key conflict -> ctrl+alt+a is a polish letter

But my version works anyway so no need for that 😉 Now I've noticed that this forum messes up with less-than and greater-than signs, the correct script should be:

#IfWinActive ahk_class AgWinMainFrame
<^>!a::SendInput ~a
+<^>!a::SendInput ~A

Perhaps should have mentioned that you need the Unicode version of Autohotkey, available afaik at ahkscript.org

I pay for software. So... I wait ;)
Maybe we can use this solution but hundreds and even thousands users still have a big problem.

It may not be good but it works and with the modified script I pasted above it preserves both AltGr+a mapping for ą and Ctrl+Alt+A mapping for "Select all flagged phots", so it's a win-win. The only solution without installing anything would be if Adobe fixed this in Lightroom which they didn't manage to for at least last 4 years. So you can either use this imperfect solution or wait, possibly forever, until Adobe does their job.

Install other things to solve problem in other software. This isn't good solution.

As discussed in later posts in this thread, making these additions to TranslatedStrings.txt doesn't fully fix the problem, and AutoHotkey is the only workaround that works.

Sending unicode characters didn't work for me, after changing the script to send tilde+a/A works flawlessly:

#IfWinActive ahk_class AgWinMainFrame
!a::SendInput ~a
+!a::SendInput ~A

This solution is hard to use ase there is no Polish translation in Lightroom and there's no TranslatedStrings.txt for English language 99% of Polish people use.
AutoHotKey doesn't require modifiying Lightroom files and is 100% non-intrusive. TranslatedStrings.txt will probably get overwritten after each Lightroom upgrade.

I fully agree that using Autohotkey is not a great solution.
