zle | Zle : An extension to Zend Framework library | Application Framework library

$path=(find xxx |fzf) is wrong. You want:

The OP confirmed that a global alias for l was defined, which altered the set of arguments seen by find, leading to the error.

The CURSOR value is handled in Zsh's source code, which is implemented in the C programming language: https://github.com/zsh-users/zsh/blob/3c93497eb701d8f220bc32d38e1f12bfb534c390/Src/Zle/zle_params.c#L266

There is no way for you to declare a similarly constrained variable in Zsh shell code.

However, you can write a math function for it instead:

You can select the vicmd keymap either by name (bindkey -M vicmd ...) or with the -a option.

To unbind the key, you can use the -r option.

To display messages in a zle widget, you're supposed to use zle -M rather than echo. echo will output your message at whatever the current cursor position is which isn't especially helpful. If you really want to use echo, calling zle reset-prompt afterwards will redraw a fresh prompt. If you don't want a potential mess in your terminal, consider starting with \r to move the cursor to the beginning of the line and ending with $termcap[ce] to clear to the end of the line.

I solved it by adding the line autoload -Uz compinit && compinit near the start of my ~/.zshrc.

Hope this helps someone!

You can do that. It's not as elegant or straight forward as with zsh but it's doable in bash using bind.
You can not only bind built in Readline functions (listed with bind -l) but other macros and shell functions too.

bind -m emacs -x '"\C-i":"cd .."' will bind a shell command (cd ..) to the keys (Ctrl+i) in emacs mode (the default mode). (Ctrl+i is unbound by default, u isn't)

Note that your prompt will probably not reflect the change.
If you leave out -x the string will instead be typed out for you so "cd ..\n" achieves the same result.

Edit: bind is how you bind keys and macros can accomplish what you want even though no built in thing exists.

If you end your PS1 prompt with \033[K (erase to eol) and can use
bind -m emacs '"\C-i":" cd ..&&echo -e \"\\033[2A\"\n"' to do what you want.
This will first print cd .. then control chars to move the cursor up and run it (with \n). The end of your PS1 prevents it from showing. This is a hack but it shows that it's doable.

I think the easiest and the quickest approach would be to shuffle your W1/Wyb1 members each time you ask a new question.

Currently you set them up once at the start of OnCreate. Just write another function which will reassign those fields in a Random manner just before your first line in run(), or to be more precise - before W1.setText(String.valueOf(c));

Below is a pseudo-code (I'm writting it in edit-box) that should prove (or not) if this approach will fit your need.
