Re: Select Whole, When There are Multiple Lines

[Ahmad Ismail <ismail783@xxxxxxxxx>]

I did not notice it earlier. The following also works.
....
_select-whole() {
    zle beginning-of-buffer-or-history
    ((REGION_ACTIVE)) || zle set-mark-command
    zle end-of-buffer-or-history
}

zle -N _select-whole
bindkey '^A' _select-whole
....
However, it works weirdly when used on single line.

What can I do so that _select-whole works on both single and multi-lines?

Thanks and Best Regards,
Ahmad Ismail
