Dear Mikael & Bart,

yes, both solutions work.

Taking into account that there are more keymaps, I think that the best solution would be to remap the keys *only* for the emacs keymap, leaving the other keymaps untouched.

bindkey -M emacs ' ' expand_abbreviations

But alas, this changes the behavior of isearch, too. The documentation is really sometimes too wordy and, in cases like this, too terse.

I believe you could also do

zle -N magic-space _expand_abbreviations
bindkey ' ' magic-space

because the isearch keymap already understands what (not) to do with
magic-space.
