Optionally keeping literal effect of key in addition to binding

Problem / Steps to reproduce

When binding a key to an action, it is sometimes desirable that hitting that key will trigger the action but also produce the usual effect it would produce otherwise in the query input.
The clearest example/use-case I have is this:
When using fzf to interface outputs from some underlying search engine (say FTS via SQLite) it may be desirable to query the engine only when full words are available (i.e. when we hit Space).
With fzf --bind 'space:reload(...)', this would get the desired effect of triggering the underlying search action only when we complete words. But currently binding space to an action will make it impossible to introduce spaces in the query line, because it gets absorbed by the binding action.

I searched through the documentation and couldn't find any feature to enable this, nor any workaround.

Not sure how complex/desirable it might be to enable this feature, but it seems quite desirable as a counterpart for the reload action.

Thoughts? Ideas on workarounds?
