You are right! I did indeed change the program's interface language to Russian. But what does the keyboard have to do with that? And what key should I press when copying files if I want to confirm that all the files being copied should overwrite the existing ones in the destination folder?
I switched the interface language back to English, and Alt+L works again.

I have just tested it and it still works. See how the L is underlined in the drop down menu (when opened with keyboard - e.g. with Down key). That indicates that Alt+L works (and it indeed does for me). Just guessing: Aren't you using some translation? The shortcut can be different in other languages.

Hi!
Version 6.5.7 2026-09-09. Alt+L stop work. Noway to use only keyboard for "Yes to All". :(

ОК. Thank you!

I didn't mean that your proposal does not make sense.
It's just the the Shift-click functionality was introduced to make the additional options easily accessible for mouse control. For keyboard control, there were already existing accelerators. So there was no real need to implement the Shift+Enter.
I will see, if more people ask for this.

What the reason of this? Why not Shift+Enter? I press Shift – name of button has changed. IMHO to press Enter at that moment is more logical, isn't it?

That's how it is intended to work. To use only keyboard, just press Alt+L.

6.5.3 Version

Try to upload a lot of files to site. Some files with the same name presents on site (old version). I select files in local folder, press Upload, in Upload window press "OK", in "Confirm" windows press Shift+Enter to upload and overwrite all files, but no reaction. Button "Yes to All" in focus, but keyboard not work. I can use mouse only. Why?
