Heh, using the zulip windows app, I somehow zoomed in by accident so my text is quite large. Now I can't zoom out (the menu item does ... nothing)...
Ctrl + 0 work by any chance?
maybe ctrl minus (on the keypad) ?
also ctrl + mouse wheel may do something
none of those worked, but doing a "Factory Reset" seemed to work
somewhat disturbingly, after that I was able to re-add the rust-lang org without entering a password :P
