Hello,
I have `bindkey -M emacs '^W' kill-region` in my zshrc and using it without
having set any mark will cut from the beginning of the line to the cursor.
I've tried to read zle's doc but found no mention of this behaviour.
Any idea about what's happening and how to do nothing if the mark isn't set?

Internally, there is actually no notion of the mark not being set ---
it's simply initialised to zero, and moved when ask it to be set.
Therefore, if you try and use it, it appears as if it's at the start of
the line.
The documentation doesn't make this explicit. It could do with
mentioning the default state.

Thanks, that's what I supposed too. I almost have it fixed with
markset=
my-set-mark()
{
zle set-mark-command
markset=true
}
my-kill-region()
{
[ $markset ] && zle kill-region
}
zle -N my-kill-region
zle -N my-set-mark
bindkey -M emacs '^@' my-set-mark
bindkey -M emacs '^W' my-kill-region
But I don't know how to reset markset every newline (other than doing an ugly
bindkey for Return).

Disregard this, I just forgot to reset markset in the second widget.

REGION_ACTIVE (integer)
Indicates if the region is currently active. It can be
assigned 0 or
1 to deactivate and activate the region
respectively. A value of 2
activates the region in line-wise mode with the
highlighted text
extending for whole lines only; see Character Highlighting below.

Thanks, this the perfect solution (I saw it, but didn't understand it when
reading the man). Now, I wonder why it's no the default.
