If you've got "compinit" in your .zshrc, you've been near hundreds of
widgets.  "Widget" is just the zsh name for a function that is
executed by ZLE.

zle-line-finish is a "special" widget that ZLE runs automatically just
after accept-line (the widget normally bound to Enter/Return).  By
default it's not defined at all, so you have to create it.

Like that.

"In" the widget just means still running the commands of the shell function.

The important bit is that you should NOT call "eval" of anything, and
that the assignment to BUFFER contains the command line you want to
run.  So if you want to keep using _execute, you would likely replace
the "eval" by the assignment of BUFFER=.

https://www.zsh.org/mla/ although I believe searching is still broken
so you need to know an article number or pore over the indexes.

zle-line-finish runs before preexec and is also always available.
However, you can't do in preexec what your ,H thing does, for two
reasons:  First, preexec can't change what is going to be executed, it
can only examine it.  Second, preexec is called after aliasing,
globbing, etc., happens, so you can't get at the partly-rewritten
command line that you want.
