issue with using arrow keys on the numeric keypad

[Evgeniyuzbek]

Describe the bug

Same issue as in applications were created by Fyne.
My OS is Ubuntu 24.04.4. I've tried cogentcore demo Text editors. I used to work with arrow keys on the numeric keypad, but on cogentcore demo Text editors it don't work. I suppose all applications by cogentcore will have same issue.
Other applications work with arrow keys on the numeric keypad well.

How to reproduce

Reprodusing was described in "Describe the bug"

Could you open the settings window (Command+,) , then click on the Debug tab, and toggle the Key event trace on, and report what you get when you hit those keys? I don't have such a numeric keypad available to me. The output will be in the console where you start the app.

Sorry, I did not understand how "open the settings window (Command+,)". BTW, I use Gnome desktop environment. There is xev application, which writes keyboard and mouse events. I think it will be helpful. If no, please write.
I attached photo of numeric keypad.

I wrote keypress events only with all of keys which are invisible for "cogentcore demo Text". Every keypress event is in own block:

Yeah those codes are unfortunately not helpful. You can run the demo app in examples/demo, and then hit the mac command key and the , comma at the same time, or do the right mouse button (ctrl + click, or double-finger tap on trackpad), and select Settings. That opens a dialog. you may need to also click the Event trace as well to see the raw key code.

I am sorry. When I created ticket I did not see topic "Platform" and default value macOS. I've replaced "Platform" to
Linux 6.17.0-14, Ubuntu 24.04.4
