I recently upgraded my Git for Windows installation to version 2.33 (by downloading the installer from https://git-scm.com).
After I did that, keyboard shortcuts no longer work in Git Bash. For example, Alt+Space no longer activates the window's menu, as it used to do. I can still, however, access it with the mouse:
As can be seen in the screen shot, the Edit menu advertises various additional (standard) keyboard shortcuts, such as Ctrl+M. These also worked before I upgraded my Git installation, but now none of them work.
I've tried to examine the window Properties, but shortcuts look like they ought to be enabled:
How do I get my keyboard shortcuts back?
