Zle, the line editor from zsh offers two main modes to browse history:
the one emulated in histdb-interactive.zsh, inspired of bash CTRL + R interactive search
a more concise syntax from tcsh world "up-line-or-beginning-search" and "down-line-or-beginning-search" where you can search by writing the first letters of your query, then [up] key (or down to scroll back)
To emulate that we would need a function allowing to open the query buffer through _histdb_isearch_query then directly do the _histdb-isearch-up without ofering any special interactive mode.

Could zsh-histdb support that mode?
