@WhiteNoise you might want to still consider this a bug.
It’s possible to map the key combination, but then it doesn’t work. (EDIT: Actually it does work, if you have focus outside of a text field. For example, I focused on a tab, and then the alt-f hotkey works for me.)
So probably it should be blocked from being mapped, or honored for those who choose to map it.
Right now it just silently fails.
