Hello,
I upgraded to Code::Blocks 20.03 (64Bit) and copied the cbKeyBinder10.ini into the new installation.
All my user defined keyboard shortcuts work, however not the ones I assigned with keys from the numeric keypad.
I use e.g. ALT-9 to open a Tool. It is shown as Alt-ō in the Settings (as was before with 17.12), but it doesn't work. A '○' appears in my code instead.
Using Ctrl-ō instead does also not work.
The Plugin Manager shows version '2.0.11 2020/03/2' for the 'Keyboard shortcuts' plugin. I guess that's the newest version?
