Comment 4 for bug 1852179

Same as the previous comments:

* gimp has been working perfectly fine for months

Suddenly, shortcuts do not work:

* Keyboard shortcuts for tool selection like pressing "R" for rectangle select is not working.
* Also the main menu does not open if I press ALT+F (for File menu).
* Alt shows underlined character but nothing happens.
* Ctrl-o doesn't do anything

Gimp is the only affected application.

Using Ubuntu 20.04, gimp 2.10.18 from default apt sources.

Tried `sudo apt install --reinstall gimp` to no avail.
