Add Cmd+Shift+- for decreasing font size on macOS.
Do not add Cmd+= for increasing size, because it conflicts with the
existing shortcut for "Replace and Find Next".
Sprinkle some Backspace shortcuts in addition to Delete for removing
items. There are (laptop) keyboards that either do not have a designated
Delete key (requiring Fn+Backspace) or where the Delete key is not
conveniently located/sized, and there is no benefit in making the
distinction in that case anyhow.

At least TagCurrentChanged can be triggered with a nullptr tag. That
means the current tag is reset to "none". We should thus handle nullptr
in all receivers of beginTagChange and endTagChange.
