I use these suffix aliases to open programs occasionally.

    alias -g G='| grep'
    alias -g R='| rg'
    alias -g L='| less'
    alias -g V='| vim -'
    alias -g S='| subl'

And if I want Zsh to auto-expand it out to type the full command (after pressing space), add this to end of your .zshrc:

    globalias() {
        if [[ $LBUFFER =~ '[A-Z0-9]+$' ]]; then
            zle _expand_alias
            zle expand-word
        fi
        zle self-insert
    }
    zle -N globalias
    bindkey " " globalias # space key to expand globalalias

Identical examples:

    grep -rw --exclude-dir={test,build} 'throw' L
    grep -rw --exclude-dir={test,build} 'throw' | less
