I want the history search to be activated when I press the up arrow after typing a statement prefix. The search should be initialized with that prefix. So, if I type "alt" then up arrow, I want to search for the last statement that started with "alt". And then up arrow and down arrow would cycle through commands with that prefix.

You get that in bash with this:

bind '"\e[A":history-search-backward'
bind '"\e[B":history-search-forward'

I think it's inspired by Matlab's console, and it's so good! I never want to use a terminal without it again.
