The Bug

I want to assign a function key, in my case F4 to a command, here Run Current Set. However I cannot make it recognized in the Shortcuts panel, it stays "". Using modifiers (Ctrl, Shift...) in combination works, though.

Steps To Reproduce

1. Open Shortcuts panel
2. Click on Run Current Test "Set" button =? shows "press buttons"
3. Type F4
4. Notice how message just reverts to "" instead of "F4", but you can still see the Cancel button being active

5. Repeat 3 but type Ctrl+F4 or Shift+F4 or Alt+F5 (don't try Alt+F4, it will close the window! And Alt+F1 etc. may be taken by Nvidia or whatever...)

(but Shift+F4 is Uppercase in code editor which will capture the input event and defeat the point of having a global shortcut)
