Hotkey disabled in 2.8.2 b1291

[matm]

Hello

Using 32 bit edition, hotkey for Go Up has no effect, whatever the key I set.

Can anyone confirm or do I have a mess in my config files ?

Regards

same edition 2.8.2 b1291 - 32bit
I use backspace and it works fine for me.

Worked back after modifying to another key (Ctrl-F12) and back again. Don't know if it came from MC or my PC...
